| Outline of Final Research Achievements |
From the viewpoint of communication efficiency, we studied the performance of the 5th generation system with the aim of improving a Massive MIMO system that can realize bidirectional user scheduling in uplink and downlink without CSI estimation. A method of reducing residual interference by maximizing the kurtosis using the fourth moment, called user selection and Robust ICA using only the analog beam, has been shown to be effective by conducting an evaluation using an actual system. confirmed.
