As the next generation wireless communication technology of 3GPP, Long Term Evolution for railway, known as LTE-R, is proposed to provide railway communication services including railway control, passenger services, wireless surveillance video, etc. The main goal of this paper is to evaluate the detailed performance of LTE-R on the WINNER D2a channel model which has been presented as an appropriate choice for the wireless channel model in high-speed scenario, and implement a LTE-R transceiver based on LabVIEW software and National Instruments Universal Software Radio Peripheral 2920 (NI USRP2920) platform for further research. The experimental results show that LTE-R has promising potential to be used in high-speed railway scenario.

This paper presents the results of measurements of LTE signal for commercial mobile devices on board of a train with the velocity of 80 to 100 km/h along the railway track. This study aims to measure the quality of the cellular LTE coverage from Kelana Jaya to Gombak considering the fact of the growing demand for better quality of service from the subscriber. The measurement is performed by conducting a drive test at the frequency range of 1800 MHz in a commercial network where the results are obtained using the G-Net Track. The measurement results present that the quality of the LTE network has not yet reached the standard specified by 3GPP standard in terms of RSRP, SINR, and data rate. The operators in Malaysia can reap the benefits from the measurement results provided in the study for future LTE deployments along the railway track.

In high-speed railways, the wireless channel and network topology change rapidly due to the high-speed movement of trains and the constant change of the location of communication equipment. The topology is affected by channel noise, making accurate channel estimation more difficult. Therefore, the way to obtain accurate channel state information (CSI) is the greatest challenge. In this paper, a two-stage channel-estimation method based on generative adversarial networks (cGAN) is proposed for MIMO-OFDM systems in high-mobility scenarios. The complex channel matrix is treated as an image, and the cGAN is trained against it to generate a more realistic channel image. In addition, the noise2noise (N2N) algorithm is used to denoise the pilot signal received by the base station to improve the estimation quality. Simulation experiments have shown the proposed N2N-cGAN algorithm has better robustness. In particular, the N2N-cGAN algorithm can be adapted to the case of fewer pilot sequences.
... Since the state of the rail network environment is dynamic, the historical network state is an important reference factor for computing offloading actions. If the decision is only made based on the current state, the decision-making behavior made by the agent would lack foresight [34]. Benefiting from the reward worth decaying, DRL algorithm can use existing decisions to drive the long-term benefits of the system, taking into account the long-term impact of decision-making behavior in the future. ...

With the rapidly increase demand on reliable wireless communication for rail scenarios, especially for real-time services, the resource limitations of on-board users are becoming increasingly prominent. The mobile edge computing (MEC) technology can expand the computing capability of terminal equipment with the edge server and reduce the end-to-end delay in the communication structure. To meet the requirements on the response delay of task execution of on-board users, deploying MEC servers in the rail communication system could be an efficient scheme. In this paper, a task offloading scheme based on task preprocessing deep deterministic policy gradient (TP-DDPG) algorithm is proposed, and a cache-assisted framework is introduced. Considering the high-speed characteristics of trains, a relevant environment interaction model is designed by using agents and interactive training to obtain an optimized task offloading and resource allocation scheme. Simulation results show that compared with other algorithms, the proposed algorithm can effectively reduce the system delay and improve the quality of service.

The accurate channel state information (CSI) is important to realize the high-reliability and high-efficiency transmission. So far, most of the conventional methods reconstruct CSI on non-RS position by the interpolation. However, high-speed mobility leads to the significant nonlinear channel variation and the performance of conventional methods is so poor that the reliability of transmission deteriorates a lot. In this paper, a novel real-time channel prediction algorithm based on convolutional neural network (CNN) is proposed, which uses the latest reference signal (RS) for online training and extracts the temporal features of channel, followed by prediction employing the optimal model. For high-speed moving scenario, the proposed algorithm is conducted in Orthogonal Frequency Division Multiplexing (OFDM) systems, e.g., long-term evolution (LTE) and fifth generation (5G) systems to track the fast time-varying and non-stationary channel via the real-time RS-based training algorithm, and obtains the accurate CSI without modification of the radio frame. Evaluated by experiments, the proposed algorithm outperforms conventional methods a lot, and more improvement could be achieved in the higher speed.

Cooperative communication is a promising method for increasing the capacity and extending the coverage between a base station (BS) and a mobile user (MU) by using relays to exploit cooperative diversity. However, the existing literature mainly focuses on theoretical performance evaluation without experimental validation and, thus, fails to address the effects on real-world radio signal propagation. This research, therefore, aims to develop a prototype amplify-and-forward (AF) relay using software-defined radio (SDR) to evaluate the real-world performance of such a relay in improving coverage. The proposed relay is developed using the LabVIEW software and programmed on a National Instruments-Universal Software Radio Peripheral 2922 (NI-USRP 2922) SDR platform. The major merit of this entire communication setup is less expensive as the system uses a reprogrammable hardware. The measurements are performed indoors, and the signal strength or received power at the MU in cases with and without the relay is recorded. The results show that the received power performance and signal-to-noise ratio (SNR) at the user improve significantly when the AF relay is deployed compared to when direct link point-to-point transmission without the relay is used.

In communication systems, the channel noise is usually assumed to be white and Gaussian distributed. Therefore, an optimum receiver structure designed for the additive white Gaussian noise (AWGN) channel is employed in applications. However, in wireless communication systems, noise is often caused by strong interferences. Moreover, there are other effects such as phase offset that degrade the performance of the receiver. Designing the optimum receiver for different channel models is difficult and not reasonable because channel model and channel statistics are not known at the receiver. In this paper, we propose a neural network-based approach to demodulate the transmitted signal over unknown channels. Naturally, the collection of the training data, design and training of the neural network, and finally reconfiguration of the system according to the designed neural network are implemented on software-defined digital signal processing facilities. In particular, we show that the proposed receiver is capable of jointly canceling the strong interferences and phase offset. Simulation results in various signal environments are presented to illustrate the performance of the proposed system. It is shown that the proposed approach has the same performance as the correlation demodulator structure for AWGN channels, while it has a clear advantage for unknown channel models. Moreover, it is shown that the neural network-based receiver may be used for channel estimation and equalization over Rayleigh channels. Numerical results indicate that the performance of the proposed receiver is very close to the Rayleigh theoretical bound.

High-speed rail (HSR) environments present unique challenges due to their high mobility and dense passenger traffic, resulting in dynamic and unpredictable task generation patterns. Mobile Edge Computing (MEC) has emerged as a transformative paradigm to address these challenges by deploying computation resources closer to end-users. However, the limited resources of MEC servers necessitate efficient task partitioning, wherein a single task is divided into multiple sub-tasks for parallel processing across MEC servers. In the context of HSR environments, the task partitioning ratio is pivotal in ensuring quality of service (QoS) and optimizing resource utilization, particularly under dynamic and high-demand conditions. This paper proposes a deep reinforcement learning (DRL)-based task partitioning mechanism using Twin Delayed Deep Deterministic Policy Gradient (TD3) for HSR environments with MEC servers (MECSs). The proposed method dynamically adjusts task partitioning ratios by leveraging real-time information about task characteristics and server load conditions. The experimental results show that when the task arrival rate is 20, the delay is improved by about 5% compared to random and about 13% compared to no_partition. When it is 50, there is no significant difference from random and about 2% improvement compared to no_partition. The task throughput is almost the same when it is 20. However, when it is 50, random is much better. We also looked at the performance change according to the number of serving MECSs. In this process, we can also note the research direction of finding an appropriate number of serving MECSs K. The results highlight the efficacy of DRL-based approaches in dynamically adapting to the unique characteristics of HSR environments, achieving optimal resource allocation and maintaining high QoS. This paper contributes to advancing task partitioning strategies for HSR systems and lays the groundwork for future research in MEC-based HSR systems.

In this paper, we investigate a new communication system architecture for ERTMS/ETCS, the most advanced standard for managing and controlling of railway traffic, integrating Public Land Mobile Networks (PLMNs), usually offering best-effort packet services only, with a Quality of Service (QoS) guaranteed satellite network, as a cost-effective substitution for dedicated 4G and 5G networks that should replace GSM-R, the current standard now at the end of its life cycle. Integration among those heterogeneous networks is provided by the Multi-path TCP protocol (MPTCP). As illustrated in the paper, proper setting of MPTCP add and drop subflow and priority handling logics allows to realize an efficient seamless vertical handover, compliant with railway requirements concerning availability, throughput, and latency.

Long Term Evolution for Railway (LTE-R) is commonly believed to be the next generation wireless communication system for high speed railway. The main objective of this paper is to assess the performance of LTE-R under realistic conditions using a hybrid high speed railway channel model involving WINNER II Channel Model that was refined and validated using measurements made within the WP1 Channel Model work package in Europe, high speed train channel model in 3GPP and large-scaled models based on a group of measurements on Zhengzhou-Xian passenger dedicated line in China. The paper presents a detailed evaluation of the BER and PSD for LTE-R suitably dimensioned for the high speed railway channel. The investigation includes analysis of the Doppler shift caused by the velocity of transmitter and receiver, the multipath interference due to reflections and diffractions from terrains in the radio service coverage area, and other serious impairing factors. The results show that LTE-R has promising potential to be used in a high speed railway environment.

On the basis of research of wireless channel models and the railway radio propagation environment, the WINNER D2a model is presented as an appropriate choice for the wireless channel for high-speed railways, and the WINNER D2a Hardware-in-the-Loop (HIL) simulation testbench is constructed for the mobile communication system. Compared to traditional computer simulation, the HIL simulation testbench can achieve higher accuracy and better real-time capability and test the on-line performance of high-speed railway equipment in laboratory. The relationship between the performance of the mobile communication system and different train speeds, co-channel interferences and received levels is simulated on the testbench. Simulation results show that train speeds and co-channel interferences make a tremendous impact on the performance of the mobile communication system whereas received levels show no obvious influence. Finally, some technical measures are proposed for improvement in system performance.

As a next generation railroad communication technology, 3GPP has been considered to provide railroad communication using LTE, known as LTE-R, including railroad control, passenger services, wireless surveillance video, etc. International Union of Railways (UIC) has commenced to generate LTE-R requirements. There are some technical challenges for LTE to be used for today's railroad communications because of the mobility of train up to 430km/h. Since railroad communication is related to public safety, very tight reliability requirement also needs to be met. In this paper, some technical considerations of LTE-R in terms of the possible frequency bands are provided. Upper limit of frequency band for high-speed train up to 500km/h is suggested by investigating the Doppler spread of wireless channel and physical channel structure of LTE.

The use of decision directed (DD) channel estimation in a multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) downlink receiver is studied in this paper. The 3GPP long term evolution (LTE) based pilot structure is used as a benchmark. The space-alternating generalized expectation-maximization (SAGE) algorithm is used to improve the performance from that of the pilot symbol based least-squares (LS) channel estimator. The DD channel estimation improves the performance with high user velocities, where the pilot symbol density is not sufficient. It can also be used to reduce the pilot overhead without any performance degradation. Minimum mean square error (MMSE) filtering can also be used in estimating the channel in between pilot symbols. The pilot based LS, MMSE and the SAGE channel estimators are implemented and the performance-complexity trade-offs are studied.

In this paper, we propose a quasi-orthogonal space-time block coding (QO-STBC) orthogonal frequency-division multiplex (OFDM) scheme for its application in frequency-selective channels. A novel decoding approach for QO-STBC OFDM is introduced, and it works based on an array-processing technique. The received QO-STBC OFDM symbol array is decomposed by null spaces of the split-up channel matrices, followed by a parallel decoding unit, as an effort to reduce the computational complexity and latency induced by the decoding process. The performance of the proposed system is evaluated over frequency-selective channels by both analysis and computer simulations to show the effectiveness of the scheme.

Along with the developments of the high-speed railway, higher and higher technical requirements for the high-speed railway mobile communication system are raised. Since the “Global System for Mobile Communications Railways” (GSM-R) implemented today is based on GSM, the new technology in GSM evolution can be used in the highspeed railway mobile communication system to adapt to the new requirements. This paper introduces a high-speed railway mobile communication system based on “Long Term Evolution” (LTE), describes its network architecture, and especially analyzes the technical advantages and application value of the system in the high-speed railway wireless communication comparing with the existing GSM-R system. It also discusses feasibility of the GSM-R system's evolution to this high-speed railway mobile communication system and proposes the possible evolution model.

Space-time coding for fading channels is a communication technique that realizes the diversity benefits of multiple transmit antennas. Previous work in this area has focused on the narrowband flat fading case where spatial diversity only is available. We investigate the use of space-time coding in OFDM-based broadband systems where both spatial and frequency diversity are available. We consider a strategy which basically consists of coding across OFDM tones and is therefore called space-frequency coding. For a spatial broadband channel model taking into account physical propagation parameters and antenna spacing, we derive the design criteria for space-frequency codes and we show that space-time codes designed to achieve full spatial diversity in the narrowband case will in general not achieve full space-frequency diversity. Specifically, we show that the Alamouti (see IEEE J. Sel. Areas Comm., vol.16, p.1451-58, 1998) scheme across tones fails to exploit frequency diversity. For a given set of propagation parameters and given antenna spacing, we establish the maximum achievable diversity order. Finally, we provide simulation results studying the influence of delay spread, propagation parameters, and antenna spacing on the performance of space-frequency codes
