Outage probability of coded cooperation over Nakagami-m fading channels and cooperation level

摘要

In coded cooperation, diversity is enhanced since cooperating nodes transmit different parts of a coded packet on different channels. In this paper, we investigate the outage probability behavior of coded cooperation relaying strategies over Nakagami-m fading channels. An exact expression for the outage probability is derived using the statistical characteristic of the signal-to-noise ratio. We also perform Monte-Carlo simulations to verify the analytical results. Then the level of cooperation is investigated by simulation, which plays an important role on the performance of the system. Finally we obtain the best cooperation level under different cases.
