METHOD AND SYSTEM OF LINEARIZATION FOR NON-LINEAR SYSTEM

摘要

The present disclosure provides a method of linearization for a non-linear system, comprising: a group of steps comprising: inputting (302) an input signal to the non-linear system; obtaining (304) an output signal from the non-linear system in response to the input signal being input to the non-linear system; obtaining (306) a desired signal for the non-linear system; comparing (308) the output signal with the desired signal, to determine (310) whether the input signal is a target signal for the non-linear system to achieve a desired performance; and in response to determining (310) that the input signal is not the target signal for the non-linear system to achieve the desired performance, generating (316) an updated signal in frequency domain by applying a coefficient to eliminate a difference between the output signal and the desired signal, for updating the input signal to the non-linear system. The present disclosure also provides a corresponding device, computer programs, and computer-readable storage.
