본 논문에서는 관찰 신호를 여러 신호 구성 요소로 분해하여 알려지지 않은 주파수 선택 채널을 통한 직접 시퀀스 코드 분할 다중 접속(DS-CDMA) 시스템을 위한 새로운 반복 터보 다중 사용자 검출기를 개발합니다. 각 분리 신호 사용자에 대한 ISI 채널을 나타내는 가상 격자 모델은 단일 채널 디코더와의 사전 정보 교환을 위해 BCJR 알고리즘 측면에서 외부 확률을 생성하도록 설계되었습니다. MKL(Minimum Kullback-Leibler) 프레임워크는 수치적 채널 추정 및 외부 확률을 계산하기 위해 파생됩니다. 다른 유사한 수신기와 비교하여 시뮬레이션 결과는 제안된 솔루션이 원하는 성능을 달성한다는 것을 보여줍니다.

Abstract: In this paper, we develop a new iterative turbo multiuser detector for direct sequence code-division multiple access (DS-CDMA) systems over unknown frequency-selective channels by decomposing the observation signal into a number of signal components. Virtual trellis model representing the ISI channel for each separating signal user is designed to generate extrinsic probability in term of BCJR algorithm for exchange with a single channel decoder as priori information. Minimum kullback-leibler (MKL) framework is derived to calculate numerical channel estimation and extrinsic probability. In comparison with other similar receiver, simulation results demonstrate that the proposed solution achieves the desirable performance.
