Title
(KO) 풀-듀플렉스 MIMO 중계기에서의 자체-간섭 억제
Abstract
(KO)
무선 통신을 위한 중계기(306)에서 자체-간섭 억제를 위한 방법 및 장치로서, 상기 중계기(306)는, 송신기(301)로부터 송신된 수신 신호 r(n)를 수신하고, 자체-간섭 억제된 송신 신호 x(n)를 수신기(305)로 송신하기 위해 배열된다. 자체-간섭 억제된 송신 신호 x(n)는, 수신 억제 필터 매트릭스 W(302)를 결정하는 단계(402)와,송신 억제 필터 매트릭스 W(304)를 결정하는 단계(403)와, 억제 필터와 증폭 매트릭스를 수신 신호 r(n)에 인가함으로써, 달성된다. r r r t
