Outage Performance of OFDM-Based Selective Decode-and-Forward Cooperative Networks Over Nakagami-m Fading Channels

摘要

In this paper, we investigate the outage performance of OFDM-based selective decode-and-forward cooperative networks over independent but not necessarily identically distributed (i.n.i.d.) Nakagami-m fading channels, with integer values of parameter m. A unified closed-form expression for the outage probability is derived for three selective relaying schemes. The effect of the coherence bandwidth on the proposed scheme is also investigated. Monte Carlo simulations are carried out to validate our analysis.
