Distortion compensation system

摘要

An address generator for compensating non-linear distortion of a transmitting amplifier according to this invention includes transmission power calculation means (201) for calculating transmission power based on transmission data, a comparator control circuit(202), and an address generation table(203). The address generation table(203) comprises a plurality of comparators operating in parallel. The comparator control circuit(202) turns on only necessary comparators based on the transmission power value so as to reduce power consumption.
