摘要： A transmitter includes a first pre-distortion circuit, a second pre-distortion circuit, a transmitting circuit and a pre-distortion parameters generating circuit. The first pre-distortion circuit uses a plurality of first pre-distortion parameters to perform a pre-distortion operation upon a first input signal to generate a pre-distorted first input signal. The second pre-distortion circuit uses a plurality of second pre-distortion parameters to perform a pre-distortion operation upon a second input signal to generate a pre-distorted second input signal. The transmitting circuit is arranged to process the pre-distorted first input signal and the pre-distorted second input signal to generate an output signal. The pre-distortion parameters generating circuit generates the first pre-distortion parameters and the second pre-distortion parameters according to the first input signal, the second input signal and the output signal.
