Abstract: This application discloses a communication method, apparatus, and system, and belongs to the field of communication technologies. The method includes: After obtaining a first digital signal sent by a transmitting end, a first receiving end performs digital signal processing on a first sub-signal in the first digital signal. A communication system in which the first receiving end is located includes the transmitting end and a plurality of receiving ends, the transmitting end is communicatively connected to the plurality of receiving ends, and the first receiving end is any one of the plurality of receiving ends. The first sub-signal is determined based on a receiving slot corresponding to the first receiving end, and different receiving ends in the plurality of receiving ends correspond to different receiving slots.

Abstract: Embodiments of the present disclosure provide example frequency domain equalization methods, example equalizers, example optical receivers, and example systems. One example method includes obtaining, by an optical receiver, a first complex signal. The first complex signal is a first time domain signal. The first complex signal is obtained based on two channels of mutually independent digital electrical signals. The optical receiver converts the first complex signal into a frequency domain signal, and multiplies the first complex signal in frequency domain by a tap coefficient to obtain a second complex signal. The tap coefficient is used to implement signal compensation for the first complex signal in frequency domain. The optical receiver converts the second complex signal into a second time domain signal, divides the second time domain signal into two channels of real signals, and outputs the two channels of the real signals.
