Incremental-best-relay selection scheme in coded cooperative networks

Incremental relaying is introduced to the multi-nodes coded cooperative system. The Incremental-Best-Relay selection scheme in coded cooperative networks is proposed based on opportunistic relaying selection strategy. The outage probability and average spectral efficiency are analyzed and simulated. Simulation results show that the proposed scheme can achieve higher average spectral efficiency while keep the same outage probability as opportunistic relaying-coded cooperation, and an optimal average spectral efficiency also can be found as the average ratio of signal to noise (SNR) is fixed.
