ABSTRACT:
A multipath interference reduction system for mobile subscriber access systems, each occupying one of a plurality of time slot channels. Interference caused by multipath returns is eliminated in the receiver portion of digital signal communications apparatus by a plurality of cascaded signal subtraction units wherein the detected signal is successively delayed by increasing multiples of the pulsewidth of the main lobe, varied in amplitude and subtracted from itself until all the multipath amplitudes of significance are subtracted out of the composite received signal.
