Cooperative ARQ protocols for dual-hop systems
Maymouna Ben Said, Hatem Boujemâa · 2010
In this paper, we analyze the performance of a cooperative ARQ protocol in terms of throughput efficiency over a dual-hop Rayleigh fading channel. Three basic ARQ strategies are considered, the stop and wait, the go back N and the selective repeat. Two relaying methods are discussed: amplify and forward (AF) versus decode and forward (DF). Finally, simulation results are provided to validate our analysis.
