METHOD FOR LINEARIZING DIGITAL PREDISTORTION OF POWER AMPLIFIER

摘要

A digital improved distortion compensation method of a power amplifier linearizing signal distorted in the power amplifier is provided to improve the linearity of the power amplifier and compensate the linearity of power amplifier. A digital improved distortion compensation method of the power amplifier is as follows. The signal inputted with the power amplifier the voltage series is used the predistortion step is distorted in advance. A training stage is distorted previously the signal outputted from the power amplifier. The training stage includes the coefficient having the error signal of the signal distorted through the distortion error disciplined through the training stage.
