A modulation/demodulation receiver having a reference signal in a digital communication system. A method for signal processing and co-channel interference signal removal in the receiver includes the steps of processing an input signal to be at a predetermined multilevel, feeding the processed signal to an adaptive equalizer, determining the type of multilevel from the signal applied to the adaptive equalizer and selecting an operation mode from at least two multilevel operation modes, for the adaptive equalizer and blocks downstream from the adaptive equalizer, and causing the adaptive equalizer to adaptively equalize the signal at the predetermined multilevel in the selected operation mode and remove co-channel interference.
