wherein L represents the tap length of the equalizer, heq represents the tap coefficient of the equalizer, noise(n− m) represents a noise amount that is at an (n−m)th sampling point and that exists before time-domain equalization processing is performed, and σaverage is an average noise amount at different level amplitudes;
quantizing the level amplitude of the sampled electrical signal to obtain W levels, wherein W is a positive integer; and
obtaining the association between level amplitudes and noise amounts at consecutive sampling points based on the calculation manner of noiseeq(n), wherein the association between level amplitudes and noise amounts at consecutive sampling points comprises WP noise amounts associated with level amplitudes at the P consecutive sampling points.
