Abstract
A signal predistortion method applied to a transmission device. The transmission device includes a signal processing circuit, a transmission chain and a power amplifier, the power amplifier is configured to amplify a radio-frequency (RF) input signal outputted by the transmission chain to generate a RF output signal. The signal predistortion method includes: performing a first signal processing operation on a baseband signal by the signal processing circuit, to generate an in-band predistortion output; performing a second signal processing operation on the in-band predistortion output by the signal processing circuit, to generate an out-of-band predistortion output; and generating a full-band predistortion signal to the transmission chain according to the in-band predistortion output and the out-of-band predistortion output by the signal processing circuit, so that the transmission chain generates the RF input signal according to the full-band predistortion signal.
