Executive Summary

Recently, the Multi-User Multiple Input Multiple Output (MU-MIMO) system has attracted much attention as a technology that enhances the total system capacity by generating a virtual MIMO channel between a base station and multiple terminal stations. Although extensive evaluations are needed because the number of system parameters in MU - MIMO is much larger compared to the Single User (SU) - MIMO, the performance of MU - MIMO in actual environments is still not well understood. This paper describes the features and effectiveness of a 16?16 Multi-User (MU)- MIMO testbed in an actual indoor environment.
