“…The approximate thresholds that achieve full diversity are also provided. Note that the main difference between this paper and reference [10] is that the destination is equipped with multiple antennas. This leads to a study of a more generalized multiantenna DF relay network.…”

“…Unfortunately, designing the optimal thresholds to minimize the average bit-error-rate (BER) of the system relies on the MATLAB Optimization Toolbox and a theoretical analysis of the diversity order is not available. Reference [10] proposes to employ the maximum energy selection (MES) receiver, i.e., selecting the maximum output from the square-law detectors of all branches to perform a detection, for a thresholdbased (i.e., adaptive) DF cooperative system. The results in [10] show that the system achieves a full diversity order with the approximate thresholds.…”

This paper studies a maximum energy selection receiver for an adaptive decode-and-forward (DF) cooperative wireless system with multiple-antenna equipped destination. In particular, the destination selects the maximum output from all the outputs of the square-law detectors to perform the detection of the transmitted information. A close-form expression for the bit-error-rate (BER) is analytically derived when the system is deployed with binary frequency-shift keying (BFSK) modulation. The thresholds used at the relays to address the issue of error propagation are optimized to minimize the BER. While finding the optimal thresholds requires information on the average signal-to-noise ratios (SNRs) of all the transmission links in the system, the approximate thresholds at each relay that require only information on the average SNR of the source-corresponding relay are investigated. It is also derived that the system achieves a full diversity order with the approximate thresholds. Finally, both analytical and simulation results are provided to verify our analysis.

“…The main two techniques proposed to overcome this problem are differential PSK where the data is transmitted through the phase difference between two consecutive symbols and the noncoherent frequency shift keying (FSK). The studies given in [10][11][12] and [15][16][17][18] investigate the performance of differential modulation technique and non-coherent FSK signaling in wireless cooperative systems, respectively.…”

Network coding has recently received significant attention as an innovative approach to improve the throughput of wireless communication systems. The multiple access relay channel (MARC), in which multiple users communicate with a common destination via a relay, is one of the important network coding applications for wireless cooperative communications. In this paper, link adaptive relaying (LAR) approach which combats performance degradation due to error propagation in digital relaying based wireless networks has been applied to the MARC model with noncoherent binary frequency shift keying (BFSK) and differential binary phase shift keying (DPSK) signalings which are among the prominent techniques for eliminating the need for channel estimation by training sequences. Simulation results for Nakagami-m fading channels have shown that the proposed MARC model with LAR scheme outperforms the noncooperative system that involves direct transmissions and overcome the diversity gain reduction due to error propagation.Keywords-Link adaptive relaying; multiple access relay channel; network coding; noncoherent binary frequency shift keying; differential binary phase shift keying.
