Outage analysis and diversity-multiplexing tradeoff bounds for opportunistic relaying coded cooperation and distributed space-time coding coded cooperation

摘要

In this paper, we analyze the outage probability of coded cooperation in opportunistic relaying (OR-CC) and distributed space-time coding (DSTC-CC) cooperative communication systems at arbitrary signal to noise ratios (SNRs) and number of available relays assuming Rayleigh fading channels. Furthermore, we obtain lower and upaper bounds for the diversity multiplexing tradeoff (DMT) for OR-CC and DSTC-CC schemes in the cases where the source node is/is not included in the cooperation. Simulation results confirm our analysis.
