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...
This paper analyzes the performance of cooperative relay networks using adaptive decode-and-forward (DF) relaying in two-wave with diffuse power (TWDP) fading channels. Among the multiple parallel relays that participate in transmission, only the relays that successfully decode the source message retransmit the signals to the destination. At the destination, the direct signals from the source and...
In this paper, a two-hop amplify-and-forward cooperative diversity system using OFDM modulation was considered. We proposed an associated waterfllling power allocation scheme under separate power constraints at source and relay, which allocated source and relay power in an associated fashion. The scheme first allocated power to subcarriers uniformly, then gave an approximate equivalent channel gain...
