MIMO(Multiple-Input-Multiple-Output) 무선 시스템은 결합된 안테나 요소 등 다양한 요인으로 인한 채널 상관 문제와 전파 환경의 키홀 효과로 인해 완전한 공간 다중화 이득을 항상 얻을 수 없습니다. 본 논문에서는 고차 다중화 이득을 감당할 수 없는 관련 MIMO 무선 채널의 순위 결핍 문제를 해결하기 위한 채널 재구성 기법을 제안했습니다. 제안된 접근 방식에서 각 이동국은 다중 액세스 간섭을 억제하기 위해 MMSE 기반 수신 빔형성기 세트를 통해 여러 기지국으로부터 여러 개의 독립적인 데이터 스트림을 동시에 수신할 수 있습니다. 각 수신 모바일에서 단일 안테나 효과를 가상으로 생성하는 수신 빔포밍을 활용하면 송신 기지국이 MIMO 다운링크 채널을 재구성한 다음 동일 채널 간섭을 사전 취소할 수 있습니다. MMSE 수신 가중치와 전송 프리코더를 반복적으로 최적화하는 제안된 신호 처리 메커니즘은 재구성된 MIMO 시스템에서 풍부한 무선 채널을 갖는 실내 MIMO 시스템에서만 볼 수 있는 높은 데이터 처리량을 제공합니다. M4 시스템은 기존 MIMO 시스템에 비해 링크된 기지국 수에 비례하여 훨씬 더 높은 용량을 달성할 수 있는 것으로 나타났다.

Abstract: Multiple-input-multiple-output (MIMO) wireless systems can not always have full spatial multiplexing gain due to the channel correlation problem caused by various factors such as the coupled antenna elements, and the key-hole effect of the propagation environment. In this paper, we proposed a channel reconfiguration technique to combat the rank deficiency problem of the involved MIMO wireless channels that can not afford high-order multiplexing gains. In the proposed approach, each mobile station can simultaneously receive several independent data streams from multiple base stations through a set of MMSE-based receive beamformers to suppress the multiple access interferences. Making use of the receive beamforming, which virtually produce the effect of a single antenna at each receive mobile, makes the transmit base station possible to reconfigure the MIMO downlink channel and then pre-cancel the co-channel interferences. The proposed signal processing mechanism that iteratively optimized the MMSE receive weights and the transmit precoders, which brings the reconfigured MIMO system about the high data throughput seen only with indoor MIMO systems having rich wireless channels. It is shown that as compared to the conventional MIMO system, the M4 system can achieve a significantly higher capacity which is proportional to the number of the linked base stations.
