| Abstract(in English) | Recently, the distributed antenna system (DAS) is under extensive investigation, since DAS has potential advantages such as reducing transmission power and increasing system throughput. This paper considers the multiple base station (BS)-cooperated DAS downlink. We apply our previously reported multiuser MIMO precoding scheme called the layered partially non-orthogonal block diagonalization (BD) with adaptive interference admission control (AIAC). The layered BD with AIAC is applicable when some of the instantaneous channel state information (CSI) feedback between the user equipment and the respective BSs are missing if the path loss between the user equipment and BS is larger than the predetermined threshold. The simulation results show that the layered BD with AIAC in the combination of multi-BS-cooperated DAS increases the system throughput (average and worst user throughput) compared to the conventional transmission techniques more than the case with centralized antenna arrangement. |
