| Abstract(in English) | MU-MIMO (Multi-User Multiple Input Multiple Output) has been considered as a fundamental technology for simultaneous communications between a base station and multiple users. As a method of implementing MU-MIMO downlink, Block Diagonalization (BD) was proposed in which the transmission weights are determined to cancel interference between multiple user terminals. On the other hand, authors proposed the Block Maximum Signal-to-Noise ratio (BMSN) which determines the transmission weights to enhance the gain for each user terminal in addition to the interference cancellation. However, there are some performances in the BMSN that it is difficult to give reasons for. In this paper, therefore, to clarify further the features of BMSN, we evaluated the BER performance of the BD and some BMSN-based methods. As a result, BMSN with an adaptive control of pseudo-noise in individual users showed the best BER performance. |
