Abstract: 본 발명은 나눗셈이 없어 고속처리가 가능한 주파수 영역 채널 보상 회로에 관한 것으로, 상기 주파수 영역 채널 보상회로는, 파일럿 신호의 채널 통과 후 에러를 추정함으로써 파일럿 채널 보상 계수를 근사화 하는 파일럿 채널 보상회로; 및 초기 심벌 계수를 상기 파일럿 채널 보상회로의 출력에 의존하여 필터계수를 개선하는 단일 탭 등화기를 포함한다. 이는, 기존의 구조와는 달리 파일럿 신호를 이용해서 빠른(fast) 페이딩에서 생긴 왜곡을 먼저 보상하고 채널과 심벌의 간섭을 단일 탭 등화기로 제거하는 회로로서, 채널 보상 계수의 근사화시 나눗셈 연산이 일어나지 않기 때문에, 회로의 동작속도와 크기에서 이점을 가진다.
