Abstract

Cooperative transmission is an efficient technique to realize diversity gain in wireless fading channels via a distributed way. In this paper, we consider a wireless network composed of a source, two parallel relays and a destination terminal. We exploit the limited feedback from the destination and propose cooperative ARQ protocols for two parallel relays. An analysis model to analyze and compare the data link layer packet error rate (PER) and throughput of cooperative transmission with joint relay selection and cooperative ARQ protocols for two parallel relays in slow fading wireless channel is established. Furthermore, The performance of this scheme are evaluated through numerical analysis and Monte-Carlo simulations and it is demonstrated that the proposed scheme can always achieve the lowest packet error rate (PER) and the highest throughput.
