Claim:
1. A transmitter, comprising: a first pre-distortion circuit, arranged to receive a first input signal and a second input signal, and use a plurality of first pre-distortion parameters and the second input signal to perform a pre-distortion operation upon the first input signal to generate a first pre-distorted input signal; a second pre-distortion circuit, arranged to receive the first input signal and the second input signal, and use a plurality of second pre-distortion parameters and the first input signal to perform a pre-distortion operation upon the second input signal to generate a second pre-distorted input signal; a transmitting circuit, coupled to the first pre-distortion circuit and the second pre-distortion circuit, and arranged to process the first pre-distorted input signal and the second pre-distorted input signal to generate an output signal; and a pre-distortion parameter generating circuit, coupled to the first pre-distortion circuit, the second pre-distortion circuit and the transmitting circuit, and arranged to generate the plurality of first pre-distortion parameters and the plurality of second pre-distortion parameters according to the first input signal, the second input signal and the output signal; wherein the pre-distortion parameter generating circuit comprises:
