Abstract(in English) Multiple-input multiple-output (MIMO) transmission have been proposed as an effective scheme to improve the spectral efficiency in wireless communications. In MIMO systems, the higher spectral efficiency is achieved by using more antennas. However, it is hard to equip mobile stations with many antennas. Therefore, multi-user MIMO (MU-MIMO) system using collaborative interference cancellation scheme is proposed. In this scheme, received signal sharing between collaborated mobile stations is employed. These collaborated stations are regarded as one station equipped with many antennas. In this paper, MU-MIMO system using collaborative maximum likelihood detection is proposed and investigated. The bit error performance is evaluated by comparison with the system using minimum mean square error filter.
