1. A method of discriminating a desired signal having a wide frequency band and including sequential symbols representing digital values, the desired signal being discriminated from a narrow band interfering signal having a carrier frequency in the wide band, the method comprising initially applying both of the signals to a filter so both signals are passed to an output of the filter, responding to the filter output to derive estimates of the values of received symbols of the desired signal, comparing the filter output with the estimated values of the received symbols to derive an error representing signal, and controlling a characteristic of the filter in response to the error representing signal so the filter is adjusted to reject the interfering signal and pass the desired signal.
