Performance of Cooperative Diversity with Constellation Rearrangement in Multi-hop Wireless Networks
2015
The purpose of this paper is to evaluate the performance of cooperative diversity in distributed grouped two-hop and multi-hop relaying networks consisting of single-antenna terminals with constellation rearrangement. Simulation results, for phase shift keyed and quadrature amplitude modulation signals in the single carrier Rayleigh channel, show that the use of the cooperative diversity with a constellation rearrangement scheme improve the error probability performance in a power constrained, grouped multi-hop relaying network operating in a multi-path fading environment. The performance of the system will be improved without reduction of Transmission rate by using constellation rearrangement. Finally, the proposed scheme is evaluated through NS2 simulation from the view of throughput in order to investigate the interaction between physical layer and MAC layer.
