A method and system for adjusting the amplitude and phase characteristics of
wireless
communication signals generated by an analog radio transmitter, based on transmit
power control (TPC) signals received by a base station (BS) and known characteristics
of a power amplifier (PA) included in the transmitter. A digital pre-distortion
compensation module, having real and imaginary signal paths, receives and processes
real and imaginary signal components used to generate the wireless communication
signal. The phase and amplitude characteristics of the wireless communication signal
are controlled in response to the TPC signals, such that impaired amplitude and
phase characteristics of the PA are corrected.
