Abstract

We proposed a multi-input multi-output automatic repeat request (MIMO-ARQ) scheme using double multi-strata space-time code (D-MSSTC) for high spectral efficiency in $4{\times}N_r$ MIMO systems. To improve error performance of the proposed scheme, we allocate power and phase to each layer of MSSTC over every transmission. Additionally, we suboptimally optimize power allocation to maximize the minimum coding gain distance of D-MSSTC and phase allocation to efficiently minimize inter-layer interference in MSSTC. In simulation results, it is observed that the proposed MIMO-ARQ scheme based on D-MSSTC shows better block error rate (BLER) performance than conventional schemes.

본 논문에서는 $4{\times}N_r$ MIMO 시스템에서 높은 스펙트럼 효율을 갖기 위해 D-MSSTC를 이용한 MIMO-ARQ 기법을 제안하였다. 제안된 기법의 오류 성능 향상을 위해, 매 전송 시 마다 MSSTC의 각 계층에 전력과 위상을 할당하였다. 추가로, 할당된 전력은 D-MSSTC의 최소 코딩 이득 거리가 최대화가 되도록 그리고 할당된 위상은 계층간의 간섭이 효율적으로 최소화 되도록 최적화를 수행하였다. 모의 실험 결과, 제안된 D-MSSTC 기반의 MIMO-ARQ 기법이 다른 기법들에 비해 우수한 성능을 얻음을 확인하였다.
