A Study on Multi cells and Multi users MIMO Transmissionwith Whitening Filters at both Base and Mobile Stations

Abstract (in Japanese) (See Japanese page) 
(in English) MIMO (Multiple-Input Multiple-Output) transmission technologies which can increase the system capacity within the same frequency bandwidth offer ultra high-speed data transmission with multiple antennas at both transmitter and receiver in wireless communications systems. Unfortunately, MIMO performance in multi-cell/multi-user environments is degraded due to the interference from inner and outer cells. In this paper, we propose a novel MIMO transmission method for the downlink in multi-cell/multi-user environments. The proposed method uses whitening filters at both the transmitter and the receiver to reduce the interference from inner and outer cells, respectively. We evaluate the performance of proposed transmission method.
