DISTORTION COMPENSATOR APPARATUS, AMPLIFIER APPARATUS, TRANSMITTER, AND METHOD OF COMPENSATING DISTORTION

摘要

This distortion compensator apparatus is a distortion compensator apparatus compensating nonlinearity of an amplifier and includes: a memory storing a compensation parameter used for correcting an input signal of the amplifier; a compensator correcting the input signal of the amplifier based on the compensation parameter; and an update controller updating the compensation parameter according to an operation state of the amplifier.
