Transmitting method and transmitting apparatus

Ideal nonlinear distortion compensation is realized by removing an imperfection of amplitude delay characteristic and an affection of inherent deviation that an amplifier has. A linear distortion compensation factor calculating part estimates, based on quadrature demodulated signals (I′ch, Q′ch), the linear distortion characteristic occurring mainly due to imperfection of analog circuits, such as a quadrature modulator and a high-power amplifier, and calculates and outputs a linear distortion compensation factor for compensating the linear distortion. A linear distortion compensating part performs a pre-distortion (addition of a reverse characteristic of the linear distortion characteristic) by multiplying the baseband signals (Ich, Qch) by the data of the linear distortion compensation factor.
