Abstract
A method and system for determining at least one DC offset compensation value used to suppress carrier leakage occurring on real and imaginary signal paths in an analog radio transmitter when a significant temperature change in the transmitter is detected. At least one DC offset signal having a level that corresponds to the at least one DC offset compensation value is provided to a digital DC offset compensation module which adjusts the DC level of at least one of the real and imaginary signal paths.
