Abstract :
This paper considers cooperative networks in independent and non-identical two-wave with diffuse power (TWDP) fading channels using opportunistic amplify-and-forward (AF) relaying. We derive new closed-form expressions for the outage probability and symbol error rate (SER) in the high signal-to-noise ratio (SNR) regime. Such expressions can be applied to opportunistic AF relaying networks consisting of an arbitrary number of relays, and in different channel fading scenarios. By analyzing the asymptotic results, we analyze the diversity order and the coding gain of opportunistic AF relaying networks.
