DISTORTION COMPENSATION CONTROLLER AND DISTORTION COMPENSATION 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 holding means for storing a distortion correction coefficient having reverse characteristics to the burst distortion; means for multiplying the distortion correction coefficient read out from the holding means by the input signal or adding the distortion correction coefficient read out from the holding 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, the distortion correction coefficient of the last time, and a signal fed back as an output signal of the transmission amplifier, the distortion correction coefficient by an adaptive algorithm, and inputting the updated distortion correction coefficient to the holding means.
