Abstract:
1. A digital receiver equalization system comprising: a digitized signal input derived from an analog front-end of a digital receiver and having a relatively wide bandwidth; an analysis channelizer that decomposes the digitized signal input into a plurality of time domain analysis channels each having a relatively narrow bandwidth; a synthesis channelizer that recomposes the analysis channels after digital signal processing performed on at least a portion of the analysis channels so as to generate a digitized output signal; a channelizer domain defining digital signal processing between the analysis channelizer and the synthesis channelizer; at least a portion of the channelizer domain digital signal processing being a cascade of multiplier arrays; and at least one of the multiplier arrays having inputs that compensate for channel distortion, wherein the at least one of the multiplier arrays is responsive to complex scalar gains for adapting to the channel distortion, and wherein the at least one of the multiplier arrays is a matched filter.
