A modulation/demodulation receiver having a reference signal in a digit al communication system. A method for signal processing and cochannel 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 the multilevel from the signal applied to the adapti ve equalizer and selecting an operation mode from at least two multilevel operation modes, for the adaptive equalizer and blocks at the back of the adaptive equalizer, and causing the adaptive equalizer to adaptively equalizes the signal at the predetermined multilevel in the selected operation mode and remove cochannel interference. |
