DISTORTION CORRECTION CONTROL APPARATUS AND DISTORTION CORRECTION CONTROL METHOD

摘要

A distortion correction control apparatus is for compensating for burst distortion of a transmission amplifier caused by a burst of an input signal of a transmission target. The apparatus includes generation means for generating a distortion correction coefficient having reverse characteristics to the burst distortion; means for multiplying the distortion correction coefficient output from the generation means by the input signal or adding the distortion correction coefficient output from the generation means to the input signal, upon reception of burst information notifying of switching between presence and absence of the input signal; and update means for updating, based on the input signal and a branch signal fed back as an output signal of the transmission amplifier, parameters of functions used for adaptively generating the distortion correction coefficient, and for inputting the updated parameters to the generation means.
