In order to balance between optimality and operation efficiency of relay selection algorithm, an efficient relay selection algorithm has been raised based on bit error rate (BER) in an amplify-and-forward (AF) collaborated relay network. The algorithm, based on characters of channel statistical information and system BER, adds gain parameter of equivalent channel, sets SNR as threshold, select relay node assembly in the condition of same power, so as to minimize system BER. This algorithm has equal performance with Full Search Algorithm but with simpler calculation. Performance of the relay selection calculation BER is better than other algorithm by forwarding and preselecting an optimal relay node.
