Abstract (in Japanese) (See Japanese page) 
(in English) Multiple-input multiple-output (MIMO) systems are well known as a method to improve the throughput performance. Recently, a concept of massive (or very large) MIMO using an antenna array with an order of 100 elements has been proposed. In general, the complexity order of signal detection in such a MIMO system becomes the third power of the number of antenna elements in the least case. The authors have evaluated the belief propagation based algorithm with parallel interference cancellers and shown that it is implementable in the order of the second power of the number of elements. Here, we describe a method to use maximum ratio combining (MRC) for message fusion and evaluate BER performance. In addition, the convergence behavior is discussed by applying the extrinsic information transfer analysis.
