Application of best relay selection approach to cooperative DF IDMA systems over Rayleigh/Weibull fading channels

Abstract

This paper analyzes the performance of cooperative decode-and-forward (DF)interleave-division multiple-access (IDMA) networks with best relay selection over Rayleigh/Weibull fading environments. In the analysis, approximate outage probability (OP) and bit error probability (BEP) expressions are derived for the considered system. Further, a 2-hop DF IDMA system is also designed to compare with cooperative one. We propose OP and BEP expression for 2hop DF IDMA systems. Numerical results are obtained by changing the number of relays and the value of fading parameter in the proposed expressions.Also, simulations are provided to corroborate the exactness of the derived approximate OP and BEP expressions.

Performance analysis for non‐orthogonal multiple access (NOMA)‐based two‐way relay communication

“…The performance of relay-aided, code division multiple access-based communication systems, assuming different relaying and system scenarios such as AF [11] and DF [12] relay-based cooperative systems with Nakagami-m fading channel links, AF relaying cooperative systems with dissimilar [13] and asymmetric [14] fading channels, selective DF-based multiple relay aided cooperative communication [15], successive AF-DF relay aided cooperative communication [16], DF relaying with the best path selection-based cooperative communication [17] and finally cooperative communication with transmitter pre-processing [18], has been explored in different works. Finally, recently, the performance of cooperative interleave-division multiple-access systems, assuming multiple DF relays and Rayleigh [19], Nakagami-m [20] and Weibull [19,21] fading channel scenarios, has also been reported by various authors.…”

“…The constants k u and r u denote the upper limit of summation, which can be set suitably depending on the desired accuracy level of the final computed values. Finally, combining (19) and 29, the sum-rate ergodic capacity for the system can be obtained as (see (30)) .…”

A Novel Multiuser Detection and Channel Estimation Method for Uplink Communication in MIMO-OFDM IDMA System

“…Moreover, the IDMA systems suffer from the co-channel and inter-symbol interference which leads to degraded performance for uplink and downlink communication in IDMA system. Currently, cooperative schemes are widely studied in these applications such as Bilim et al [21] cooperative decode and Forward cooperative scheme using best relay selection. In another study, presented in [22], authors introduced cooperative relay beamforming scheme in IDMA.…”

Relay Selection in Energy Harvesting Aided Mixed Rf/Fso System With Transmit Antenna Selection Over Atmospheric Turbulence and Pointing Error

“…Owing to deep fading, it is assumed that there is no direct link between the source and destination. Therefore, the RF links within the system are assumed to undergo Rayleigh fading distributions, and thus the PDF and CDF of the distribution can be given as [21]:…”
