Abstract
A dynamic equalization system and method for use with a receiver is provided. The receiver may include an antenna for receiving a signal having multipath signal components and a digitizer for obtaining and digitizing the received signal and multipath signal components. The digitized signal segment and multipath signal components may be discretized into signal segments of length n. Channel parameters of each of the discrete signal segments may be analyzed and locked to, and a time-domain representation of the analyzed channel parameters may be output. Each time-domain representation may be Fourier transformed into a frequency-domain representation, based upon which equalization parameters to equalize the multipath signal components for each of the analyzed channel parameters may be determined. The equalization parameters may be applied to corresponding signal segments of the digitized signal and multipath signal components so as to equalize the multipath signal components.
