Abstract
A transmitter for a communication system comprises a digital pre-distortion (DPD) circuit configured to generate a digital intermediate signal by compensating an input signal for distortions resulting from an amplifier, and an adaptation circuitry configured to update the first parameter based on the adjustment signal, the input signal, and an output signal output by the amplifier and based on the digital intermediate signal. The DPD circuit includes an infinite impulse response filter configured to implement a transfer function based on a first parameter, and thermal tracking circuitry configured to generate an adjustment signal corresponding to a thermal change of the amplifier.
