| Abstract(in English) | Multi-user multiple-input multiple-output (MU-MIMO) systems with precoding have been studied intensively. In this system, feedback delay of channel state information causes performance degradation. Therefore, an MU-MIMO system using collaborative interference cancellation is studied. In this system, received signal sharing among collaborated mobile stations is employed. These collaborated stations are regarded as one station equipped with lots of antennas. In this paper, the bit error performance of the MU-MIMO system using collaborative interference cancellation is evaluated by field experiments. As interference cancellation techniques, both linear and non-linear interference cancellation are examined. |
