Abstract
A signal processing method in a digital-domain includes: adding a random number sequence signal into a time-domain input signal to generate a time-domain processed input signal; performing a Fourier transform operation upon the time-domain processed input signal to generate a frequency-domain processed input signal; performing an equalizer operation upon the frequency-domain processed input signal to generate a frequency-domain output signal according to coefficients of the equalizer operation; performing an inverse Fourier transform operation upon the frequency-domain output signal to generate a time-domain output signal; generating a decision output signal and generating a time-domain error signal according to the time-domain output signal; and determining the coefficients according to the time-domain error signal and the frequency-domain processed input signal.
