Methods, devices and apparatuses for communication, and computer-readable medium

Abstract

Examples of the present disclosure relate to a method, device and apparatus for communication, and a computer-readable medium. An example of the method includes: conducting, based on a channel response between a transmitter and a receiver, spectral shaping on a first sequence at the transmitter, so as to obtain an intermediate sequence, where the spectral shaping at least partially counters the channel response; remapping the intermediate sequence, so as to obtain a second sequence, where the second sequence has less signal levels than the intermediate sequence; and transmitting the second sequence to the receiver, so as to train an equalizer of the receiver. In this way, the method can accelerate training of the equalizer without sacrificing performance of the equalizer or introducing any additional hardware cost.
