Peak to average power ratio reduction of ZT DFT-s-OFDM signals using improved monarch butterfly optimization-PTS scheme
Article
Full-text available
  • May 2021
For traditional orthogonal multiplexing frequency division (OFDM) systems, a novel Zero Tail Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing Division (ZT DFT-s-OFDM) waveform architecture has recently been proposed as a problem solution of low peak to average power ratio (PAPR) efficiency. The ZT DFT-s-OFDM system allows the delay in the transmission of the channel with multipath to be dynamically copied, thus the limitations to be rectified with the hard-coded Cyclic Prefix (CP). However it is affected by few roadblocks during the transmission of data, and the primary one involves the high peak-to-average power ratio (PAPR), which results in saturation observed in the power amplifier, production of more amount of interference and decreased resolution in elements such as digital/analog converters, which were considered as nonlinear. Partial transmit sequences (PTSs) is a promising plan and direct technique, ready to accomplish a viable PAPR decrease execution, yet it requires a thorough hunt to locate the ideal stage factors, which causes high computational multifaceted nature expanded with the quantity of sub-blocks. Right now, the author proposed a reduced computational complexity PTS scheme, in view of a new swarm knowledge algorithm, which is termed as Improved Monarch Butterfly Optimization (IMBO) for PAPR decrease with the ZT DFT-s-OFDM framework. The IMBO is a new swarm intelligence algorithm, with the capability of achieving an efficient optimization search that implements phase weighting process with less complexity for selecting optimum phase factors. Also, the proposed technique is quite efficient in looking for a fusion with optimal character of phase rotation factors for minimizng the computational difficulty involved. The outcomes of simulation indicate that IMBO-based PTS algorithm can substantially reduce PAPR employing an easy network structure in comparison with classical algorithms such as PTS scheme for conventional OFDM and PTS with ZT-DFT-s-OFDM.

Polynomial Cancellation Coded DFT-s-OFDM for Low-PAPR Uplink Signaling
Article
Full-text available
  • Nov 2019
The physical layer signaling of the 5G new radio still utilizes cyclic prefix orthogonal frequency division multiplexing (CP-OFDM) and discrete Fourier transform-spread-OFDM (DFT-s-OFDM) to support 5G services for the sake of system-backward compatibility. However, the transmission requirements among these services differ, and this poses a challenge to the adaptability of the waveforms with regard to the peak-to-average power ratio (PAPR) issue. In particular, DFT-s-OFDM serving as a low-PAPR option for uplink signaling still has room for PAPR improvement in cases such as machine-type and device-to-device communications. We propose polynomial cancellation coded (PCC)-DFT-s-OFDM to flexibly reduce the PAPR of conventional DFT-s-OFDM. The principle of the proposed method, including its transform, is analyzed in the time domain. The results show that it can also be regarded as a novel spectral shaping scheme for PAPR reduction. Through a parameter designed for adjusting the cost of spectral efficiency, the proposed method can regulate the extent of improvement compared with the conventional DFT-s-OFDM, not only in the PAPR, but also for the spectral radiation and bit error rate when considering the nonlinearity of the power amplifier. The increase in computational complexity is neglectable owing to the simplicity of generalized PCC, making it apt to be deployed in existing systems.

Hybrid PS–GW optimised PTS scheme for PAPR reduction in OFDM system
Article
Full-text available
  • Nov 2019
The most famous and attractive strategy used in wireless communication for huge transmission of data with higher rate was orthogonal frequency division multiplexing (OFDM) approach. Efficient methods are important for PAPR reduction in high‐speed wireless communication systems. The reduction of PAPR in OFDM system has been carried out with one of the most familiar approach called Partial transmit sequences (PTS). Various techniques are already presented for reducing the PAPR, some of them are, clipping, SLM, and PTS. From that PTS is considered as an efficient method because the PAPR was reduced by PTS without causing any signal distortion. In this work, PTS along with hybridization optimization algorithm named as PS–GW will be implemented to get the minimum performance on PAPR and computational complexity. The PS–GW is a combination of both the Particle Swarm Optimization (PSO) and Grey Wolf Optimizer (GWO) which search the optimal combination of phase rotational factors efficiently. A fundamental thought in this method was that the capacity of exploitation in PSO was enhanced with the capacity of investigation in GWO to create a two variations in quality. The results produced by this proposed method shows that the reduction was effectively determined in both PAPR and computational complexity.

A Hybrid PAPR Reduction Method Based on SLM and Multi-Data Block PTS for FBMC/OQAM Systems
Article
Full-text available
  • Oct 2018
The filter bank multicarrier employing offset quadrature amplitude modulation (FBMC/OQAM) is a candidate transmission scheme for 5G wireless communication systems. However, it has a high peak-to-average power ratio (PAPR). Due to the nature of overlapped signal structure of FBMC/OQAM, conventional PAPR reduction schemes cannot work effectively. A hybrid PAPR reduction scheme based on selective mapping (SLM) and multi data block partial transmit sequence (M-PTS) methods is proposed for FBMC/OQAM signals in this paper. Different from the simple SLM-PTS method, the proposed hybrid algorithm takes into account the overlapping effect of multiple adjacent data blocks on its PTS process. From simulation results, it can be obtained that the proposed method can offer a significant PAPR reduction performance improvement compared with the SLM, PTS and SLM-PTS methods. The proposed method can effectively reduce the PAPR in FBMC/OQAM systems.

Orthogonal Frequency Division Multiplexing (OFDM) is a very efficient multicarrier technique. OFDM is used more and more in recent wideband digital communications. It has numerous advantages such as the ability to handle severe channel conditions, efficient spectral usage, reduced inter symbol interference (ISI), and high data rate. Therefore, it has been utilized in many future wired and wireless communication systems 4G LTE mobile communications. In this paper, mainly focus on the performance evaluation and study of OFDM system over multipath fading channels such as AWGN, Rician and Rayleigh fading channels. Based on simulation results will make us understand some of these effects and signal-to-noise ratios (SNRs), channels are compared together in order to rank them according to the delivered signal. Quality of the signals, bit-error rates (BERs), and peak signal-to-noise ratios (PSNRs) of the received signals are the aspects in which system performance is evaluated.

Performance evaluation of CCOs for the optimization of low-power pressure-based implantable wireless systems
Article
  • Sep 2020
  • MICROPROCESS MICROSY
Implantable biomedical devices intended for remote follow-up of Cardiovascular Diseases (CVD) are often based on MEMS pressure sensors and the corresponding CMOS electronics, which are responsible for powering, signal conditioning and data transmission. This kind of heterogeneous systems achieves reduced dimensions and consumption by monolithic integration on the same silicon substrate. The objective of this work is to analyze and fully characterize several Capacitor-Controlled Oscillator (CCO) topologies that can be used for the aforementioned implantable applications, by comparison of their most relevant performance parameters. The results will allow the design optimization of low-power wireless implants, aimed at a future development of embedded systems with real-time data acquisition. Five topologies have been chosen for the evaluation: a standard ring oscillator; a current-starved ring oscillator; a Lee-Kim fully-differential oscillator; a coupled Sawtooth oscillator, and a modified Sawtooth oscillator designed for CCOs biased by a ramped voltage signal. Comprehensive simulations allowed the estimation of the output frequency, percentage tuning range, maximum linearity error, phase noise and power consumption for each design, as well as a Figure of Merit, for every CCO. For the calculation of these performance metrics, the impact of biasing circuits and different tuning strategies has also been considered.

A novel hybrid genetic algorithm to reduce the peak-to-average power ratio of OFDM signals
Article
  • Oct 2019
  • COMPUT ELECTR ENG
Orthogonal frequency division multiplexing (OFDM) is an effective approach for high rate data transmission in telecommunication systems. The high peak-to-average power ratio (PAPR) is one of the main drawbacks of the OFDM systems. Partial transmit sequence (PTS) is an efficient method to decrease the PAPR of OFDM signals. But, the PTS technique needs an exhaustive search over all combinations of phase rotation factors and the computational complexity grows exponentially with the number of sub-blocks. To reduce the search complexity, we introduce a novel hybrid genetic algorithm (HGA) in the PTS technique. The important aspect of the proposed method is the choice of salient phase factors to reduce the high PAPR. The proposed HGA-PTS approach incorporates novel local search operations that are designed and embedded in the genetic algorithm to explore the optimum phase factors. Numerical simulations are performed for 16-QAM modulated symbols and the obtained results show that the HGA-PTS significantly reduces both the PAPR and search complexity.

Chapter
  • Jan 2019
It is well known fact that high PAPR value degrades the performance of OFDM system. In this paper, PTS (Partial transmit sequence) based approach is opted for the reduction of PAPR and three major contributions are made to the traditional PTS scheme. First, the phase sequence that is to be multiplied is changed, second the system is extended with hybrid mechanism of SLM (selective mapping) and PTS scheme in which additional hybrid scheme is opted. Third the benefits of DHT (Discrete Hartley transform) are incorporated with this system. It is found from the experimental results that the proposed MSD (modified sequence DHT) based system able to decreases the PAPR at a considerate factor and also able to preserve the OBI (out of band interference).
