본 논문에서는 W-CDMA 상향링크에 대한 순방향-역방향 필터링 채널 추정을 이용한 다단 병렬 간섭 제거 수신기의 성능을 평가한다. 채널 추정은 원래 W-CDMA 랜덤 액세스 수신을 위해 제안된 비인과적 순방향 곱셈 방식 필터를 사용합니다. 보행자 A 및 차량 A 채널을 통한 데이터 및 음성 트래픽 시나리오에 대한 링크 수준 시뮬레이션 결과를 1슬롯 파일럿 평균화, 1슬롯 평균화 및 가중 다중 슬롯 평균화의 기존 채널 추정 방법과 비교하여 논의합니다. 순방향-역방향 필터링 채널 추정은 보행자 A 채널과 차량 A 채널 모두에서 일반 Rake 수신기뿐만 아니라 간섭 제거 수신기의 성능을 향상시키는 것으로 나타났습니다. 처리 지연이 짧고 복잡도가 낮은 특징을 지닌 순방향-역방향 필터링 채널 추정은 다단계 간섭 제거 수신기의 실제 구현에 적합합니다.

Abstract: In this paper, the performance of multi-stage parallel interference cancellation receiver using forward-backward filtering channel estimation is evaluated for the W-CDMA uplink. The channel estimation employs a non-causal forward-backward-multiplication-method filter, which was originally proposed for the reception of W-CDMA random access. Results of link level simulations for data and voice traffic scenarios over Pedestrian A and Vehicular A channels are discussed in comparison with the conventional channel estimation methods of 1-slot pilot averaging, 1-slot averaging, and weighted multiple slot averaging. It is shown that the forward-backward filtering channel estimation improves performances of the interference cancellation receiver as well as that of the ordinary Rake receiver in both Pedestrian A and Vehicular A channels. With its features of short processing delay and low complexity, the forward-backward filtering channel estimation is suitable for practical implementations of multi-stage interference cancellation receivers.
