주파수 선택형 채널을 사용하는 단일 반송파 MIMO(다중 입력 다중 출력) 시스템은 ISI(심볼 간 간섭) 및 CCI(동일 채널 간섭)로 인해 어려움을 겪습니다. 두 가지 유형의 간섭을 모두 제거하기 위해 우리는 첫 번째 단계에서 FDE(주파수 영역 등화)와 SIC(계층형 직렬 간섭 제거)를 수행하는 하이브리드 2단계 결정 피드백 등화기(HTS-DFE)를 제안합니다. ) 두 번째 단계에서. FDE나 SIC에서는 DF(Decision-Feedback) 또는 NP(Noise-Prediction) 아키텍처를 사용할 수 있으므로 제안하는 등화기는 실제로 완벽한 피드백을 가정할 때 동일한 MSE(평균 제곱 오차)를 달성하는 4가지 변형을 가질 수 있습니다. 또한 HTS-DFE와 디코딩된 결정 피드백(DDF) 방식을 결합하여 실제로 발생하는 오류 전파를 완화합니다. 시뮬레이션 결과는 제안된 HTS-DFE가 기존 이퀄라이저보다 훨씬 뛰어난 성능을 발휘할 수 있음을 확인했습니다.

Abstract: A single-carrier multiple-input multiple-output (MIMO) system with frequency-selective channels suffers from the inter-symbol interference (ISI) and the co-channel interference (CCI). To eliminate both type of interference, we propose in this letter a hybrid two-stage decision-feedback equalizer (HTS-DFE), which performs the frequency-domain equalization (FDE) in the first stage and the layered serial interference-cancellation (SIC) in the second stage. Since the decision-feedback (DF) or noise-prediction (NP) architecture can be employed in FDE or SIC, the proposed equalizer actually can have four variations that achieve the same mean square error (MSE) under the assumption of perfect feedback. Further, we combine HTS-DFE with the decoded decision-feedback (DDF) scheme to mitigate the error-propagation encountered in the practice. Simulation results confirm that the proposed HTS-DFE can outperform the existing equalizers significantly.
