Abstract
Various embodiments of the present disclosure relate to transmitter systems, methods, and instructions for signal predistortion. The transmitter system includes a signal decomposition module configured to extract a low-frequency signal (S) and a high-frequency signal (S) from an input signal (S); a distortion compensation processing module configured to generate a pre-distorted low-frequency signal (U) and a pre-distorted high-frequency signal (U) based on the received low-frequency and high-frequency signals using signal generation coefficients; a signal combining module configured to combine the pre-distorted low-frequency signal (U) and the pre-distorted high-frequency signal (U); and a signal characteristic estimation processing module configured to update the signal generation coefficients used by the distortion compensation processing module based on comparing the low-frequency signal (S) and the high-frequency signal (S) with a detected feedback low-frequency signal (Y) and a detected feedback high-frequency signal (Y).
