본 논문에서는 릴레이 필터가 SI(자체 간섭), 릴레이 간 간섭( IRI) 및 기호 간 간섭이 있습니다. 우리는 전체 릴레이 전송 전력 제약을 조건으로 신호 대 잡음 및 간섭 비율 최대화를 기반으로 하는 필터 설계 문제를 고려합니다. 문제를 다루기 쉽게 만들기 위해 우리는 두 가지 방법을 제안합니다. 하나는 SI 및 IRI에 대한 필터 응답이 널링되는 추가 제약 조건을 부과하는 방법이고, 다른 하나는 중계 전송 신호에 대해 iid 가정을 하는 방법입니다. 시뮬레이션 결과는 제안된 FD-FF 방식이 반이중 모드에서 기존 FF 방식보다 성능이 우수함을 보여줍니다. 또한 채널 경로 이득의 XNUMX차 통계만 사용할 수 있는 경우 필터 설계도 고려합니다.

Abstract: In this paper, we consider full-duplex (FD) relay networks with filter-and-forward (FF)-based multiple relays (FD-FF), where relay filters jointly mitigate self-interference (SI), inter-relay interference (IRI), and inter-symbol interference. We consider the filter design problem based on signal-to-noise-plus-interference ratio maximization subject to a total relay transmit power constraint. To make the problem tractable, we propose two methods: one that imposes an additional constraint whereby the filter responses to SI and IRI are nulled, and the other that makes i.i.d. assumptions on the relay transmit signals. Simulation results show that the proposed FD-FF scheme outperforms a conventional FF scheme in half-duplex mode. We also consider the filter design when only second-order statistics of channel path gains are available.
