| Zusammenfassung: | A method and system for providing adaptive filtering in a communication system. The method and system modify coefficients of a finite impulse response filter fed by a sequence of digital samples in accordance with an error signal in floating point format. The floating point error signal includes only a sign bit and an exponent term. The exponent term is added to an exponent term of an adaptation coefficient to produce a composite error signal. The adaptive filter is used as a linear adaptive equalizer and as an echo canceler. |
