Abstract: A digital pre-distortion (DPD) circuit includes a DPD and a power amplifier (PA). The DPD module is configured to: obtain features of a first input signal, determine a first coefficient and a second coefficient based on the features of the first input signal, generate a second signal based on the first input signal and the first coefficient, generate a first output signal based on the second signal and the second coefficient, and input the first output signal to the power amplifier. The PA is configured to amplify the first output signal to generate a second output signal.
