摘要：
A communications system receives a modulated signal that carries encoded communications data. An adaptive filter has a plurality of non-adaptive and adaptive filter taps with weighted coefficients and an adaptive gain circuit for updating the adaptive gain of the adaptive filter responsive to a received state of a modem or the type of modulation used by communications system. A demodulator and decoder receive the filtered output signal from the adaptive filter and demodulate and decode the signal to obtain the communications data.
