Dispersion compensation method and apparatus, and storage medium

A dispersion compensation method, wherein the method is applied to a transmit end, the transmit end communicates with at least two receive ends, communication distances between the transmit end and the at least two receive ends are different, the communication distance between the transmit end and each receive end comprises a first communication distance and a second communication distance, and the method comprises:

• obtaining, by the transmit end, a subcarrier allocation result, wherein the subcarrier allocation result comprises subcarriers allocated to the at least two receive ends based on signal-to-noise ratio results of signals transmitted between the transmit end and the at least two receive ends;
• compensating, by the transmit end based on a correspondence between a communication distance and a dispersion compensation value, a subcarrier allocated to each receive end for a dispersion compensation value corresponding to the first communication distance, to obtain a compensated signal;
• adding, by the transmit end, a cyclic prefix (CP) to the compensated signal;
• and
• compensating, by the transmit end, a frequency-domain subcarrier corresponding to the signal to which the CP has been added, for a dispersion compensation value corresponding to the second communication distance.
