| Summary: | Based on the capacity of multi-access channel,a relay selection algorithm was proposed.It was proposed that: relays were selected according to the eigenvalue decomposition of the equivalent relay-destination channel,and the beamforming vectors were designed in a distributed manner.It could be seen that joint processing and information trans-mission between multiple relays were avoided,which could reduce system complexity.Simulation results show that the system proposed can achieve better bit error rate（BER） comparing to the one with multi-relay parallel transmission. |
