In order to improve the reliability and validity of the MIMO(multiple input multiple output) relay communication system,it is necessary to study the relay node selection technique used in communication systems.Based on an analysis of the MIMO communication system modulation,detection and the fixed-gain relay selection technology,a wireless communication system based on MIMO fixed gain relay selection technology is designed and simulated.Simulation results show that the relay selection technique improves the transmission performance of the system overall,reduces the bit error rate and strengthens the communication system's anti-interference ability.
