Relay node contains multiple antennas and BPSK modulation is used. In these models under consideration, different optimal decision rule is determined theoretically. To generate each threshold decision rule, either instantaneous and average SNR or both together in S›D, S›R and R›D links are used. Proposed antenna selection algorithm with the optimal threshold value can reduce significantly the end-to-end BER according to the simple relaying technique. © 2013 IEEE.trinfo:eu-repo/semantics/closedAccessAntenna selectionCooperative diversitySNR based selection relayingConference Object
