MIMO 시스템을 위한 QR-LRL이라는 간단한 검출기가 제안되었으며 QR-LRL이 하드 출력 ML 성능에 근접한 것으로 나타났습니다. 그러나 소프트 출력 성능은 ML 성능에 근접할 수 없습니다. 이 편지에서 우리는 빈 벡터 집합 문제를 피하면서 신뢰할 수 있는 소프트 출력을 생성할 수 있는 새로운 감지 방법을 제안합니다. 제안된 검출기는 QR 분해에서 상부 삼각 구조를 효율적으로 사용한다. 시뮬레이션 결과는 제안된 검출기가 소프트 출력에 가까운 ML 성능과 실현 가능한 복잡성을 지닌 하드 출력에 접근할 수 있음을 보여줍니다.

Abstract: A simple detector named QR-LRL for MIMO systems was proposed in and it was shown that QR-LRL approached the hard-output ML performance. However, its soft-output performance is not capable of approaching the near ML performance. In this letter, we propose a novel detection method which can generate reliable soft-outputs while avoiding the empty vector set problem. The proposed detector efficiently uses the upper triangular structure in QR decomposition. Simulation results show that the proposed detector can approach the near soft-output ML performance as well as hard-output with feasible complexity.
