ABSTRACT:
A power calculating and amplitude limitation judging portion13calculates the power value x of the digital quadrature baseband signal I, Q from a transmission data generator1, and compares the power value x with a power threshold value y set by a threshold value setting portion14to judge whether amplitude limitation is needed or not. An amplitude maximum limiting portion12subjects the quadrature baseband signal from the transmission data generator1to the amplitude maximum value limitation based on the judgment result in the power calculating and amplitude limitation judging portion13. Thereafter, the digital quadrature baseband signal which has been subjected to the amplitude maximum value limitation by the amplitude maximum value limiting portion12is subjected to the distortion compensation using complex multiplication based on the distortion compensation data by a non-linear distortion compensation calculator2.
