dc.description.abstract본 논문에서는 블라인드 등화 후에 적용하는 블록좌표하강법 (block coordinate descent; BCD)을 이용한 후처리 기법을 제안한다. BCD를 적용하여 비컨벡스인 블라인드 등화 문제를 두 개의 부문제로 나눈다. 채널 추정과 심볼 검파의 교대 최적화를 반복한다. 수신 심볼이 충분히 많은 경우에 제안 기법은 완전한 채널 추정의 BER 성능에 도달함을 모의실험을 통해 확인한다.-
dc.description.abstractWe propose a blind equalization post processing based on block coordinate descent (BCD) methods. The proposed algorithm applies BCD methods to a blind equalization problem and divides it into two subproblems. We iteratively alternate the optimizations of channel estimation and symbol detection. Simulation experiments show that the proposed algorithm achieves the BER performance of perfect CSI when there are enough received symbols.-
