Dynamic equalization systems and methods for use with a receiver for a multipath channel

A dynamic equalization system for use with a receiver, the receiver comprising an antenna configured to receive a signal distorted by multipath signal components and a digitizer configured to obtain and digitize the signal and multipath signal components received by the antenna, the dynamic equalization system comprising:

• an equalization estimator configured to receive the digitized signal and multipath signal components from the digitizer, the equalization estimator comprising:
• acquisition circuitry configured to sequentially output discrete signal segments of length n of the digitized signal and multipath signal components;
• channel parameter loop circuitry configured to sequentially analyze and lock to channel parameters including phase, delay, and carrier frequency of the corresponding signal segment, and to output a time-domain representation of each of the analyzed channel parameters for the corresponding signal segment;
• Fourier transform circuitry configured to sequentially Fourier transform each time-domain representation into a frequency-domain representation for each of the analyzed channel parameters for the corresponding discrete signal segment, and to output the frequency-domain representation;
• and
• an equalization processor configured to determine and output equalization parameters to equalize the multipath signal components for each of the analyzed channel parameters based on the frequency-domain representations;
• an equalizer configured to sequentially receive the discrete signal segments of the digitized signal and multipath signal components from the acquisition circuitry, to sequentially receive the equalization parameters from the equalization processor, to sequentially apply the equalization parameters to the corresponding signal segments so as to equalize the multipath signal components, and to output the equalized signal segments;
• and
• alignment circuitry configured to sequentially receive the corresponding equalized signal segments from the equalizer and the analyzed channel parameters for an earliest-in-time signal component from the equalization processor and to align the earliest-in-time signal component with the equalized multipath signal components within the equalized signal segments based thereon.
