Signal pre-equalization methods, devices, terminals and storage media

Abstract

The application provides a signal pre-equalization method, device, terminal and storage medium, wherein the method comprises: receiving a digital signal sequence to be processed; determining a waveform shaping value of each symbol in the digital signal sequence based on a symbol change rate of the digital signal sequence, the symbol change rate being determined based on the number of the same symbols connected in the digital signal sequence; performing digital pre-equalization waveform shaping on the digital signal sequence based on the waveform shaping value of each symbol, and outputting a pre-equalization signal based on the shaped waveform. Compared with the prior art in which all the symbols in the digital signal sequence are uniformly subjected to waveform shaping, the signal pre-equalization method, device, terminal and storage medium provided by the application can adopt different waveform shaping values for symbols with different symbol change rates, realize adaptive pre-equalization waveform shaping, and thus improve the data transmission rate while obtaining a low-error-rate signal.
