Abstract
The invention is a divisional application of 202610037205. X. The invention discloses a signal processing method, device, equipment and system, a storage medium and a product. Performing partition processing on a to-be-processed signal output after the target signal passes through the nonlinear device to obtain a plurality of first signal regions; a preset type determination strategy is adopted to determine area types corresponding to the multiple first signal areas respectively, and the preset type determination strategy is determined based on the steep degree of the waveform shape; for each first signal area, adopting a compensation strategy matched with the area type corresponding to the current first signal area, and performing compensation processing on a sub-signal of the current first signal area in a corresponding area in the target signal by using the ideal signal to obtain a compensation signal corresponding to the current first signal area; and determining a pre-distortion signal corresponding to the ideal signal according to the compensation signals corresponding to the plurality of first signal areas. According to the invention, effective pre-distortion signals can be provided for signals with complex and changeable forms.
