In this paper, multicarrier code division multiple access (MC-CDMA) modulation is adapted to constitute wireless sensors to improve the monitoring performance of wireless sensor networks (WSNs) for underground coal mine. A subcarrier phase compensation algorithm based on selective mapping (SLM) is proposed to reduce the relatively high PAPR of MC-C...

... Based on the literature review, existing works on Code-Division Multiple Access (CDMA) systems either adopt the assumption of orthogonal subchannels [7][8][9] or have considered synchronous communications [10,11]. Furthermore, [12] investigated the performance of the CDMA in the Cooperative Communication System, which used the Maximum Ratio Combiner (MRC) and the Equal Gain Combiner (EGC). ...
Multi-path fading is a severe issue that causes fluctuations in the amplitudes of the received signals. For combating this issue, several researchers have used cooperative communication in the Long-Term Evolution (LTE)-advanced system. To further decrease the degradative effects of transmitted signals, various error correction techniques can be used to recover the erroneous components, especially when the channel has been deep fading. The paper investigates the general performance of the Convolutional Codes (CC) in the LTE-advanced cooperative system and compare it with the Bose-Chaudhuri-Hocquenghem (BCH) codes. The comparison is based on WINNER II project as the channel model between the nodes in the two coding processes. To validate the advantages of BCH code, the process were tested on three different environments; a suburban macro-cell, urban macro-cell, and the rural micro-cell with prior study to understand the appropriate relay height in every environment. Path loss models for each environment were derived and proposed as part of the proposed simulation framework. Conducted simulation studies based on bit error rate and direct connection showed that the use of the CC and the BCH codes in a relay technologies could significantly increase the system performance. It was noted that the performance of the system which used BCH nodes was better than the system using CC nodes in an LTE-advanced cooperative system.
... A power control game with pricing mechanism has been addressed for an MIMO CDMA system [7][8][9][10][11]. On the basis of that, a new utility function for different modulations with pricing for an MCCDMA is developed in this work. ...
The increasing demand for high data rate services necessitates technology advancement and adoption of beyond fourth generation (4G) termed as 5G cellular standards. The capacity of multi‐carrier code‐division multiple access (MCCDMA) systems is limited by multiple access interference (MAI), further the near–far effects and the time‐varying fading instigated by variations in the received power at the base station. However, the most significant problem that needs to be addressed is to contest profound fades, arising frequently, but for a very brief time. To further attain capacity enrichment of a multiple‐input–multiple‐output MCCDMA system, a dispersed power control game with pricing system with various modulation schemes are deliberated. This study shows that the proposed pricing scheme prove to be powerful techniques for attaining an enhanced performance as it results in growth in minimal power utilisation in an MCCDMA system.
