Abstract (in Japanese) (See Japanese page) 
(in English) In order to achieve high performance wireless communications for Beyond 5G and 6G, MIMO (Multiple-Input Multiple-Output) with multiple antennas has been considered. Several precoding methods have been proposed for MIMO that ad- just the signal before transmission, and nonlinear precoding methods have been shown to achieve better characteristics than linear precoding methods. In this paper, we focus on the VP (Vector Perturbation) method, which improves transmission characteristics by adding a new vector to the transmitted signal. To realize this technique, we have already proposed a VP method that applies the MCMC (Markov Chain Monte Carlo) method. In this study, we compare the improved method of the proposed method with the THP method, a typical nonlinear precoding method.
