In the case of large-scale MIMO (Multiple-Input Multiple-Output) communications in the downlink, it is effective to apply interference management based on channel state information (CSI). In this case, by using the estimated channel state information for uplink signal detection, it is possible to control the interference without using a feedback channel. In this paper, channel estimation is performed by utilizing independent component analysis (ICA) that can detect signals without orthogonal pilot sequences in the uplink. We will investigate the realization of high-precision mutual communication in a large-scale MIMO system without extending the pilot sequence. Computer simulation results demonstrate the proposed method is effective in capturing accurate CSI and mitigating mutual interference in the down
