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 studies expression of outage probability and partner selection strategies for cooperative network based on IDMA superposition modulation. By changing existing outage gain matrix into a symmetric new one and applying Hungary and WLF algorithm, a centralized optimal and a distributed sub-optimal partner selection strategies are proposed for superposition modulation cooperative multiple access...
In this paper, we propose a location-aware relay selection (LARS) scheme based on geographical information in the distributed opportunistic relay (OR) communication system. The scheme aims to limit the contention among potential relays through dividing the whole relay selection region into some small nonoverlapping contending torus zones. If a relay lies in the specified contending zone and its local...
