우리는 주파수 선택성 페이딩(FSF) 채널에 비해 우수한 성능을 갖는 새로운 적응형 다중 기호 차동 검출(MSDD) 방식을 제안합니다. 적응형 MSDD 방식은 결정 지연 없이 채널 추정을 수행할 수 있는 적응형 비간섭 최소 평균 제곱 채널 추정기와 MSDD로 구성됩니다. M-알고리즘은 MSDD에서 관찰된 시퀀스 길이의 증가로 인한 계산의 복잡성을 줄이기 위해 이 탐지 체계에 도입되었습니다. 적응형 채널 추정기와 M-알고리즘의 적용으로 인해 이 적응형 MSDD는 결정 지연 없이 M개의 생존 경로를 따라 모든 기호에 대해 채널 추정이 수행되는 것을 가능하게 합니다. 그리고 이 적응형 MSDD의 SER 성능은 MSDD와 비동기식 채널 추정기가 적용되므로 채널에 의해 발생하는 위상 변동에 영향을 받지 않습니다. 적응형 MSDD 방식은 일반적인 16APSK 성상도, (4,12) QAM 및 스타 QAM에 적용됩니다. FSF 채널을 통한 이 적응형 MSDD 체계의 탁월한 추적 성능은 컴퓨터 시뮬레이션을 통해 확인되었습니다.

Abstract: We propose a novel adaptive multiple-symbol differential detection (MSDD) scheme that has excellent performance over frequency selective fading (FSF) channels. The adaptive MSDD scheme consists of an adaptive noncoherent least mean square channel estimator that can accomplish channel estimation without any decision delay and the MSDD. The M-algorithm is introduced into this detection scheme to reduce the complication of computation due to increasing observed sequence length in the MSDD. Because of the application of the adaptive channel estimator and the M-algorithm, this adaptive MSDD make it possible that channel estimation is accomplished for every symbol along M surviving paths without any decision delay. And the SER performance of this adaptive MSDD is not affected by phase fluctuation introduced by a channel because the MSDD and the noncoherent channel estimator are applied. The adaptive MSDD scheme is applied to typical constellation of 16APSK, the (4,12) QAM and the star QAM. The excellent tracking performance of this adaptive MSDD scheme over FSF channels is confirmed by computer simulations.
