In a signal reception system comprising an adaptive filter (12) having a plurality of filter coefficients and producing a filtered signal, a differential detection circuit (13) for carrying out differential detection operation by the use of a delayed signal wherein the filtered signal is delayed, and an error signal generation circuit (14) for generating an error signal, the adaptive filter adjusts the plurality of filter coefficients in accordance with the error signal. An error signal control circuit (20) has a threshold value and supplies the error signal to the adaptive filter (12) only when the delayed signal has a signal value which is higher than the threshold value. <IMAGE> |
