ABSTRACT:
Apparatus and methods relating to channel equalization include a method including: generating a first output signal in a frequency domain based on a communications signal of a channel; determining a first channel response based on the first output signal and one or more pilot signals of the communications signal; generating a first equalized signal based on the first output signal and the first determined channel response; generating a first decision signal based on the first equalized signal; generating an output signal in a time domain based on the first decision signal; determining a second channel response based on the time domain output signal; generating a second output signal in the frequency domain based on the second channel response; generating a second equalized signal based on the first and second output signals and the time domain output signal; and generating a second decision signal based on the second equalized signal.
