Kyoung-Young Song, Jae‐Hong Kim, Jong‐Seon No, Habong Chung · 2010
In this paper, we propose the best relay selection scheme for the soft-decision-and-forward cooperative network with multiple relays. The term `best relay selection' implies that the relay having the largest end-to-end signal-to-noise ratio is selected to transmit in the second phase transmission. The approximate performances are analyzed in terms of pairwise error probability. Using the Fox's H-function, it is shown that the proposed scheme has full diversity order.
