Abstract
A beamforming maximum ratio combining (MRC) pre-processing system for adjacency removal of HDR includes a first filter module implemented in a digital radio receiver and allowing only a low side band signal having a frequency lower than a center frequency of a radio signal in a selected channel to pass therethrough and a processor module performing beamforming on the selected channel based on a difference in gain value between the signal that has passed through the filter module and an original signal that has not passed through the filter module.
