Claims (6)
- 아날로그-디지탈 변환기(25)와 디지탈 신호 처리부(30)를 포함하는 비선형 동작 압축을 갖는 아날로그 수신부(10)로 구성되는 위상 또는 주파수 변조 정보 신호용 무선 수신기(2)에 있어서, 상기 디지탈 신호 처리부(30)는 아날로그 수신부(10)의 비선형 동적 압축(22)을 보상하기 위한 팽창부(29)를 포함하는 것에 특징이 있는 위상 또는 주파수 변조 정보 신호용 무선 수신기.
- 제1항에 있어서, 비동적 압축(22)의 특성에 역비례하는 역함수 값은 정보 신호(e)의 디지탈화 구적성분(Id, Qd)의 각 샘플값의 쌍을 위해 팽창부(29)에서 결정되며 디지탈화 구적성분(Id, Qd)을 선형으로 평활화 하기 위해 사용되는 것에 특징이 있는 위상 또는 주파수 변조 정보 신호용 무선 수신기.
- 제1항에 있어서, 상기 팽창부(29)는 한쌍의 역함수값이 디지탈화 구적 성분(Id, Qd)의 각 샘플값의 쌍을 위하여 저장될 수 있는 테이블(T)을 포함하는 것에 특징이 있는 위상 또는 주파수 변조 정보 신호용 무선 수신기.
- 제1항에 있어서, 상기 팽창부(29)는 디지탈화 구적성분(Id, Qd)의 각 샘플값의 쌍을 위하여 확장인수가 저장될 수 있으며, 팽창된 구적성분(Iex, Qex)은 각 팽창계수와 각각의 디지탈화 구적성분(Id, Qd)의 곱으로부터 형성되는 것을 포함하는 것에 특징이 있는 위상 또는 주파수 또는 변조 정보 신호용 무선 수신기.
- 제3항 또는 제4항중 한 항에 있어서, 상기 테이블(T)의 메모리 셀은 디지탈화 구적성분(Id, Qd)의 한쌍의 샘플값에 의해서 각각 어드레스될 수 있는 것에 특징이 있는 위상 또는 주파수 변조 정보 신호용 무선 수신기.
- 제3항 또는 제4항중 한 항에 있어서, 상기 테이블(T)의 메모리 셀은 한쌍의 디지탈화 구적성분(Id, Qd) 샘플값의 예정할 수 있는 최상위 비트 수에 의해서만 어드레스될 수 있는 것에 특징이 있는 위상 또는 주파수 변조 정보 신호용 뭄선 수신기.
