Abstract
Co-channel interference in an AMPS (Advanced Mobile Phone System) receiver, having at least two diversity paths each for producing a received signal, is reduced by determining weights for combining the received signals in dependence upon the received signals and a reference signal, combining the received signals in accordance with the determined weights to produce a combined received signal, demodulating the combined received signal, and producing the reference signal by amplitude limiting the combined received signal or modulating the demodulated signal or a signal derived from the demodulated signal, so that the reference signal is produced from the combined received signal with amplitude variations reduced and with frequency variations of the desired signal substantially maintained.
