A pre-distortion apparatus and method for recovering nonlinear distortion
of a high power amplifier. The pre-distortion apparatus includes: a
demodulator for demodulating a signal outputted from the high power
amplifier, generating a demodulated signal; a first storage unit for
storing the demodulated signal outputted from the demodulator; a second
storage unit for storing a reference transmission signal outputted from a
transmitter of a transmitting system; a digital signal processor for
calculating a pre-distortion coefficient by comparing the demodulated
signal and the reference transmission signal stored at the first storage
unit and the second storage unit; and a third storage unit for storing
the pre-distortion coefficient calculated at the digital signal
processor.
