LTE M-QAM 시스템에서 MIMO 알고리즘을 적용한 하향 링크 시스템의 성능 분석

초록

In this paper, we evaluate the bit error rate (BER) performance for Downlink communication of LTE M-QAM system when MIMO decoding algorithms are employed. As the number of antennas increased, the transmission rate was increased as well. And the bigger diversity gain could be achieved when the ML(Maximum Likelihood) method, a sub-optimal algorithm in MIMO decoding algorithms, was used.
