Abstract (in Japanese) (See Japanese page) 
(in English) Distributed antenna systems have been studied to increase the system capacity by exploiting macrodivercity.
In this paper, the downlink transmission in precoded multi-user MIMO systems is considered and the impact of the positioning of base station antennas (BSAs) on the system performance is studied through field experiments.
The experimental system consists of a base station with two antennas and two mobile stations with one antenna each.
Field experiments are conducted at 5\,GHz band.
With different positionings of the BSAs and mobile stations, the received power and bit error rate at the mobile stations are given.
The results show that with distributed BSAs, the performance degradation that occurs when the mobile stations are close to each other is mitigated.
