Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we evaluate the performance of the next generation standard IEEE 802.11ac wireless local area network (WLAN) system. IEEE 802.11 for the first time will employ downlink multi-user multi-input multi-output (MU-MIMO) technology. Precoding techniques greatly influences the performance of MU-MIMO transmission. We measure these improvements when realistic channel conditions are applied. We compare the performance of channel inversion (CI) and block diagonalization (BD) precoding methods paired with various MIMO detection techniques. From the simulation results, we show the effectiveness of BD precoding compared to CI precoding.
