다중 안테나 시스템에서 다이버시티를 이용한 공간 변조 기법의 BER 성능

Abstract

In this paper, we evaluate the performance of MIMO(Multiple Input Multiple Output) system by using new method of SM(Spatial Modulation). In new SM method, three transmit antennas among four transmit antennas transmit signals to receiver. The receiver demodulates the received signal using MIRC(Maximum Ratio Combining), ML(Maximum Likeihood) method and evaluates system performance. For transmitting signal which has same data rate with SM method. Numerical result shows that proposed SM method improves bit error rate BER(Bit Error Rate) of MIMO system.
