| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The easiest way to improve the throughput performance of multiple-input multiple-output (MIMO) systems is to increase the number of both transmit and receive antennas. In general, however, algorithms detecting spatially-multiplexed signals require the complexity proportional to the third power of the number of antenna elements in the least case. Thus, the implementation of an antenna array with an order of 100 elements becomes very difficult. Several studies have shown that a detection based on the belief propagation with a parallel interference canceller is implementable in the order of the second power of the number of elements and achieves very good BER performance. In this paper, we apply three methods for the complexity reduction into the belief propagation with focus on the Tanner graph, and evaluate those BER performances. | |
