Abstract

In this paper, we propose a new adaptive MIMO switching algorithm that provides the optimal trade-off between throughput and reliability of data in MIMO system. The proposed algorithm is based on the variable packet error predictor which is robust for channel estimation error, and we show that our algorithm has a better spectrum efficiency than the conventional MIMO switching techniques about 8 percent point.

본 논문에서는 다중 안테나 시스템에서의 전송률과 안정성 측면에서의 최적의 성능을 발휘하기 위해 채널 추정오차에 강인한 적응형 다중입출력(MIMO) 스위칭 알고리즘을 제안한다. 제안된 논문은 무선 채널의 추정 오차에 대한 강인성을 확보하기 위하여 가변형 패킷오류 예측 방식에 기반을 두었으며, 기존의 MIMO 스위칭 방식에 비해 스펙트럼 효율이 약 8% 이상 증대 됨을 확인할 수 있었다.
