Zusammenfassung:The present invention relates to a communication device capable of removing interference signals, and more specifically, to a communication device which can efficiently eliminate interference signals contained in signals received via multiple routes. According to the present invention, the communication device comprises: an interference signal operation unit which operates a first feedback signal according to a predetermined method to generate and output a first operation signal, and operates a second feedback signal according to a predetermined method to generate and output a second operation signal; a first adaptive filter unit which uses the first feedback signal to generate a first interference removal signal, outputs the first interference removal signal, and uses the first operation signal to update a filter coefficient; a second adaptive filter unit which uses the second feedback signal to generate a second interference removal signal, outputs the second interference removal signal, and uses the second operation signal to update a filter coefficient; a first interference signal removal unit which uses the first interference removal signal to remove an interference signal included in a first reception signal; and a second interference signal removal unit which uses the second interference removal signal to remove an interference signal included in a second reception signal. According to the present invention, it is possible to reduce the complexity and manufacturing costs of a multi-channel communication device capable of removing interference signals. 본 발명은 간섭 신호 제거가 가능한 통신 장치에 대한 것으로서, 보다 상세하게는 멀티 복수의 경로를 통해 수신되는 각 신호에 포함된 간섭 신호를 효율적으로 제거할 수 있는 통신 장치에 대한 것이다. 본 발명에 따른 통신장치는 제1 궤환신호를 미리 설정된 방법에 따라 연산하여 제1 연산신호를 생성하여 출력하고, 제2 궤환신호를 미리 설정된 방법에 따라 연산하여 제2 연산신호를 생성하여 출력하는 간섭신호연산부, 제1 궤환신호를 이용하여 제1 간섭제거용신호를 생성하고, 제1 간섭제거용신호를 출력하되, 제1 연산신호를 이용하여 필터계수를 업데이트하는 제1 적응형필터부, 제2 궤환신호를 이용하여 제2 간섭제거용신호를 생성하고, 제2 간섭제거용신호를 출력하되, 제2 연산신호를 이용하여 필터계수를 업데이트하는 제2 적응형필터부, 제1 간섭제거용신호를 이용하여 입력된 제1 수신신호에 포함된 간섭신호를 제거하는 제1 간섭신호제거부 및 제2 간섭제거용신호를 이용하여 입력된 제2 수신신호에 포함된 간섭신호를 제거하는 제2 간섭신호제거부를 포함한다. 본 발명에 따르면 간섭신호 제거가 가능한 멀티 경로 통신장치의 복잡도 및 제조 단가를 낮출 수 있다.
