| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Tomlinson Harashima Precoding (THP) for Multi-User Multiple Input Multiple Output (MU-MIMO) system has been proposed as an effective approach to achieve near capacity to the theoretical limit in MU-MIMO channels. However, when there is some error in the channel state information (CSI), it causes a large degradation of the BER performance of THP. In this paper, we propose a method to reduce the influence of CSI error by decoding received signals with the real part of the channel estimation value. We derive the impact of CSI error on THP theoretically. Then, the proposed scheme is evaluated by the computer simulation. | |
