Interference Alignment (IA) is one of the promising technologies to solve the co-channel interference in wireless communication systems. It can effectively improve system capacity and reliability. Based on consideration of engineering applications, the realization of interference alignment for three-cell MIMO cooperative communication system is studied and then a precoding matrices group selection method based on the Maximum of total system Signal Interference Noise Ratio (Max-SINR) criterion was proposed in this paper. Firstly, all the transformation matrices in cooperative communication system are calculated and the precoding basis is selected according to the Max-SINR criterion.
