Research and Implementation of Non-uniform Distribution Random Beamforming Algorithm

Most of the hybrid CSI beamforming schemes consider the channel environment as the ideal uncorrelated channel, and do not take into account the long-term spatial correlation information of users. Most of them adopt the assumption that the users in the cell are evenly distributed around the base station, which is inconsistent with the actual wireless communication environment. According to the characteristics of non-uniform distribution of users around the base station, this paper studies two non-uniform distribution random beamforming algorithms and their implementation.
