Zusammenfassung:	Provided are a pre-distortion processing method, a device, an apparatus, and a storage medium. The method includes: determining a current envelope signal corresponding to a current radio frequency input signal; obtaining a corrected envelope signal by correcting the current envelope signal based on an envelope correction parameter table; determining, on the basis of the current envelope signal, the current radio frequency input signal and a radio frequency digital pre-distortion (DPD) parameter table, a DPD-processed radio frequency input signal ; and obtaining a current radio frequency output signal by controlling the DPD-processed radio frequency input signal based on the corrected envelope signal.
