Abstract

In this paper, we evaluate the performance of up-link multi-user MIMO systems with SM. The receiver demodulates the received signal using ML method determines the signal which seems to be the most probable after comparing the received signal and all transmitted signal candidates. When transmitting with the same data rate, the SM method shows better performance of bit error rate(BER) than that of the space shift keying(SSK) of the previously proposed multi-user system.

본 논문에서는 다중 안테나 시스템(Multiple Input Multiple Output: MIMO)를 사용하는 상향 링크 다중 사용자 환경에서 공간 변조(Spatial Modulation: SM) 기법을 사용하고, 변조된 신호를 수신 신호와 모든 송신 신호 후보를 비교하는 최대 우도(Maximum Likelihood: ML) 기법으로 복조하는 방법을 사용하여 시스템의 성능을 평가한다. 같은 데이터 율(date rate)로 전송하였을 때 공간 변조 기법이 기존에 제안된 다중 사용자 환경에서의 공간편이 방식(Space Shift Keying: SSK)보다 비트오류율(Bit Error Rate: BER) 성능이 좋아졌다.
