Relay Selection in Cooperative Diversity Systems
Yuhui Han, Mingji Yang, Aili Wang · Advanced science and technology letters · 2014
In this paper, we propose an improved relay selection scheme for single-relay decode-and-forward cooperative diversity systems, in which relays are selected according to instantaneous channel state information and a cooperative threshold is set up to eliminate some unsatisfying relays from the set of alternative relays and thus reduce the calculated amount. Simulation results show that the proposed improved relay selection scheme can achieve very high performance with low computational complexity.
