Claim Text:
1. A method for updating pre-distortion coefficients, comprising: presetting a primary table and a standby table, wherein the primary table stores default pre-distortion coefficients and the standby table stores updated pre-distortion coefficients; when a data source of a pre-distortion processor adopts the standby table, adopting the updated pre-distortion coefficients to perform parameter output processing to acquire pre-distortion parameters, and conveying the pre-distortion parameters and an input signal to the pre-distortion processor to process to acquire pre-distortion signals; conveying the pre-distortion signals through various signal processors to process to acquire a first signal, and determining the power data of the first signal; if the power data of the first signal is more than or equal to a setting range, continuing to adopt the standby table as the data source of the pre-distortion processor; and if the power data of the first signal is less than the setting range, switching the data source of the pre-distortion processor to the primary table.
