Abstract:
A method for determining pre-distortion of a power amplifier includes the following steps: providing a first power input signal to make the power amplifier generate a first power output signal; receiving a first receiving signal, which is acquired according to the first power output signal; detecting a predetermined gain of the power amplifier by means of the first power input signal and the first receiving signal; providing a second power input signal to make the power amplifier generate a second power output signal; receiving a second receiving signal, which is acquired according to the second power output signal; determining pre-distortion amplitude values and pre-distortion phase values of the power amplifier by means of the predetermined gain, the second power input signal and the second receiving signal.
