An adaptive filter (11) for use in a diversity receiver system (10) which includes circuitry (23, 24, 25, 26, 34) for determining the strongest received diversity signal or group of signals at each of a plurality of time delays or group of time delays and circuitry (27, 28, 29, 30, 31, 34) for calculating a weighting signal and for weighting only the strongest received diversity signal or group of signals at each of the time delays or group of time delays, the other received diversity signals at each time delay thereby being in effect weighted by zero. The weighted signals are then combined in a delay line (32, 33) having a plurality of taps at such time delays to produce an output receiver signal. In a particular embodiment, for example, the received signals are complex signals and the weights used for the strongest received diversity signal at each time delay are quantized weights selected from the group +/-1+/-j.
