Abstract: A method and apparatus for temperature compensation for data converters in a software defined radio. Specifically, the system and method are teach monitoring the temperature of critical signal processing components such as band pass filters, ADCs and DACs and retrieving modulator coefficients in response to the temperatures and the like. The modulator coefficients are then used to compensate for temperature changes, performance changes and the like.
