Abstract (in Japanese) (See Japanese page) 
(in English) Multi-beam massive MIMO configuration has been proposed that utilizes the beam selection with high power in an analog part and blind algorithm such as constant modulus algorithm (CMA) which does not need channel state information (CSI) in a digital part. However, when the Least Square - CMA (LS - CMA) is applied to Quadrature Amplitude Modulation (QAM) signal whose amplitude changes, the effect of interference cancellation decreases as the number of modulation order increases. In this report, we evaluate the performance in uplink multi-beam massive MIMO when applying Robust Independent Component Analysis (Robust ICA) instead of LS-CMA.
