1. A frequency domain equalization method, wherein the method comprises:
receiving at least two channels of digital electrical signals;
randomly selecting two channels of mutually independent digital electrical signals from the at least two channels of the digital electrical signals;
obtaining a first complex signal, wherein the first complex signal is a first time domain signal, and the first complex signal is obtained based on the two channels of mutually independent digital electrical signals;
converting the first complex signal into a frequency domain signal;
multiplying the first complex signal in frequency domain by a tap coefficient to obtain a second complex signal, wherein the tap coefficient is used to implement signal compensation for the first complex signal in frequency domain;
converting the second complex signal into a second time domain signal;
dividing the second time domain signal into two channels of real signals; and
outputting the two channels of real signals.
