As a method of implementing MU-MIMO (Multi-User Multiple Input and Multiple Output) downlink, Block Diagonalization (BD) algorithm is well known in which the transmission weights are determined to completely cancel interference between multiple user terminals. On the other hand, Block Maximum Signal-to-Noise ratio (BMSN) algorithm was proposed which determines the transmission weights to enhance the gain for each user terminal in addition to the interference cancellation. As a feature, BMSN has a pseudo-noise for controlling the null depth to the interference. In this paper, we make the performance analysis of BMSN algorithm in terms of receive SINR (Signal-to-Interference-plus-Noise Ratio) , and propose some kinds of modified BMSN algorithms to enhance further the performance. Via computer simulation, it is demonstrated that the proposed BMSN algorithms outperform BD algorithm and also they have individual features in forming the eigen channels of MIMO. |
