Title
Indoor Experiments On Real-Time Multiuser Mimo Transmission In Wireless Lan Systems
Abstract
This paper presents indoor experimental results on an implemented real-time downlink multiuser multiple-input multiple-output (DL-MU-MIMO) transceiver for next generation wireless LAN systems. In the transceiver, channel state information (CSI) is estimated at each station (STA) and fed back to an access point (AP) on a real-time basis. At the AP, transmit beamforming weight for DL-MU-MIMO transmission is calculated by using the estimated CSI. This paper also proposes a fast computation scheme for computing transmit weight in real time. Indoor experiments with the DL-MU-MIMO transceiver demonstrate its feasibility. The experimental results clarify that DL-MU-MIMO transmission can achieve system throughput of greater than 500 Mbit/s with simple digital signal processing of single-antenna STAs in an indoor environment.
