Abstract
A digital transmitter with sample rate digital predistortion is disclosed. The transmitter includes a digital radio frequency (RF) signal generator configured to receive a baseband digital signal and transform the baseband digital signal to a digital RF signal. The digital transmitter further includes a sample rate predistorter configured to predistort the digital RF signal so as to compensate for distortion associated with the transmitter that is generated subsequent to an output of the sample rate predistorter, and resulting in a digital predistorted RF signal. The digital transmitter further includes a digital to analog converter configured to convert the digital predistorted RF signal to analog, resulting in an analog predistorted RF signal.
