Abstract:

Cooperative communication can achieve spatial diversity gains, and consequently combats signal fading due to multipath propagation in wireless networks powerfully. A novel
complex field network-coded cooperation (CFNCC) scheme based on multi-user detection for the multiple unicast transmission is proposed. Theoretic analysis and simulation results demonstrate that, compared with the conventional cooperation (CC) scheme and network-coded cooperation (NCC) scheme, CFNCC would obtain higher network throughput and consumes less time slots. Moreover, a further investigation is made for the symbol error probability (SEP) performance of CFNCC scheme, and SEPs of CFNCC scheme are compared with those of NCC scheme in various scenarios for different signal to noise ratio (SNR) values.
