본 논문에서는 계산 복잡도를 줄이면서 기존의 소프트 입력 MLD(Maximum Likelihood Detector)보다 성능이 뛰어난 비선형 과부하 MIMO 검출기를 제안합니다. 우리는 이러한 우수한 성능을 달성하기 위해 제안된 검출기에 대한 반복적 로그 가능성 비율(LLR) 추정과 다단계 LLR 추정을 제안합니다. 반복적 LLR 추정은 더 나은 BER 성능을 달성하는 반면, 다단계 LLR 추정은 기존 소프트 입력 MLD(최대 우도 검출기)보다 검출기를 덜 복잡하게 만듭니다. 컴퓨터 시뮬레이션을 통해 제안된 검출기는 0.6×6 과부하 MIMO OFDM 시스템에서 소프트 입력 MLD의 복잡성이 약 절반으로 소프트 입력 MLD보다 약 3dB 더 나은 BER 성능을 달성한다는 것을 보여줍니다.

Abstract: This paper proposes a non-linear overloaded MIMO detector that outperforms the conventional soft-input maximum likelihood detector (MLD) with less computational complexity. We propose iterative log-likelihood ratio (LLR) estimation and multi stage LLR estimation for the proposed detector to achieve such superior performance. While the iterative LLR estimation achieves better BER performance, the multi stage LLR estimation makes the detector less complex than the conventional soft-input maximum likelihood detector (MLD). The computer simulation reveals that the proposed detector achieves about 0.6dB better BER performance than the soft-input MLD with about half of the soft-input MLD's complexity in a 6×3 overloaded MIMO OFDM system.
