블록좌표하강법을 이용한 블라인드 등화 후처리 기법

초록

We 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.
