Summary:
MIMO (Multiple-Input Multiple-Output) transmission technologies with multiple antennas at both transmitter and receiver are attracting attention for realizing ultra high bit rate data transmission in wireless communications. Unfortunately, the MIMO performance in multi-user radio access systems can be degraded due to the interference from inner and outer cells. In this paper, we propose a novel MIMO transmission method for the downlink of mobile radio access systems in multi-cell/multiuser 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 the proposed transmission method.
