Abstract:
A method for signal processing is provided. The method includes: obtaining a predistortion signal for compensating nonlinear distortion generated by a transmission path; adding the predistortion signal to the transmission path to compensate the nonlinear distortion; and outputting the nonlinear distortion compensated signal by the transmission path. With the above method, the nonlinear distortion of the transmission path can be compensated without modifying a current transmission path, thereby enhancing transmission performance of a transmitter by using a simple structure.
