Uplink MU-MIMO techniques achieve the high frequency efficiency. However, it is known that the frequency efficiency depends on the arrangement of antennas of the access point. Moreover, we have proposed the distributed antenna system (DAS) which selects the high density arranged antennas according to user distribution and shown its effectiveness using narrow band signals in an actual indoor environment. For the actual implementation, this paper proposes an antenna selection methods that selects the antenna in a limited area and selects the antenna in a non-limited area. We compare the basic characteristics of the DAS when applied the uplink MU-MIMO by broadband OFDM signals in an indoor environment for each selection method, and demonstrate the effectiveness of DAS with the proposed antenna selection methods. |
