Based on minimum mean square error of detected signal at destination node, a new transfer matrix design algorithm is proposed to improve the performance of multiple input multiple output (MIMO) relay communication systems. A major purpose of this algorithm is to solve AX+XB=F type matrix equation. Through singular value decomposition method, the final optimal transfer matrix can be got at last. Linear precoding and linear detection based on zero forcing criterion is adopted owing to simplicity. Through algorithm analysis and simulation comparison, the ergodic capacity improvement margin is about 2 bit&middots-1&middotHz-1, better than the unitary matrix method under same simulation configuration.
