Abstract (in Japanese) (See Japanese page) 
(in English) The easiest way to improve the throughput performance of multiple-input multiple-output (MIMO) systems is increasing the number of both transmit and receive antennas. In general, however, algorithms detecting spatially-multiplexed signals require the complexity to be proportional to the third power of the number of antenna elements at least. 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 uncorrelated MIMO channels. However, it is expected that the detection performance degrades in spatially correlated MIMO channels. In this paper, we propose applying node selection, and show the BER performance in correlated channels.
