description PURPOSE: A blind equalization method for a high definition television signal is provided to conduct the blind equalization of an ATSC(Advanced Television Systems Committee)-High Definition Television signal and any other one-dimensional modulation system. CONSTITUTION: An adaptive equalizer updates tap coefficients thereof with the aid of an error signal, e(k) = sign£z(k)|*(Rs- absolute value z(k) ¬2), where sign£| is a sign function, z is an equalizer output(z) at a symbol time, an absolute value is a magnitude function, Rs is a positive real constant, which is optimally defined as Rs = E (absolute value an ¬3) / E (absolute value an). A generalized equalizer error signal satisfies e(k) = sign£z(k)|*(Rsp - absolute value z(k)¬p) where Rsp is a positive real constant, which is optimally defined as Rsp = E (absolute value an¬(p+1)) / E (absolute value an) and p is a positive integer. 적응 등화기는 에러 신호인를 통해 자신의 탭 계수를 갱신하는데, 여기서 sign[]은 사인 함수이고, z(k)는 심볼 시간(k)에서의 등화기 출력이고, ∥는 크기 함수이며, R는 양의 실수인 상수이며, 상기 R는로서 최적으로 정의되는데, 여기서 E{}는 수학적인 예상 함수이고, a은 심볼 시간(n)에서의 정보 심볼이다. 일반화된 등화기 에러 신호는를 충족시키는데, 여기서 R는 양의 실수인 상수이고, 상기 R는로서 최적으로 정의되며, p는 양의 정수이다. 등화기는 ATSC(Advanced Television Systems Committee)-고선명 텔레비전 신호 및 임의의 다른 일차원적인 변조 시스템의 블라인드 등화를 실행한다.
