초록

ML디코딩이 복잡도와 전송시간이 덜 소요되는 고차 안테나의 시공간코드를 제안한다. 이 때 제안한 것이 부분간섭제거 알고리즘이다. 제안된 알고리즘은 심벌을 층(Layered)으로 구분하고 동등한 채널행렬을 만들고 그룹으로 디코딩한다. 이렇게 했을 때 전송시간과 디코딩 복잡도가 줄어들었고 성능이 비직교에 비해 좋아졌다.

Because of increasing complexity in maximum-likelihood (ML) decoding of four of higher antenna scenario, Partial Interference Cancellation (PIC) group decoding could be the perfect solution to reduce the decoding complexity occurs in ML decoding. In this paper, we separate the symbols the users in the layered basis and find the equivalent channel matrix. Based on the equivalent channel matrix we provide the grouping scheme. In our paper, we construct a block wise transmission technique which will achieve the desired code rate and reduce the complexity and provide less transmission time. Finally we show the different grouping performance.
