Power Allocation of Relay Selection in Coordinated Channel Based on Channel Statistical Information

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,...
