ABSTRACT:
Systems and methods for providing baseband predistortion within a transmitter. In a simplified embodiment, the transmitter contains a main signal path that receives an input signal and generates a main signal in response thereto. A filter in the main signal path is used for removing unwanted signal components from the main signal. A power amplifier having non-linearity is also located within the transmitter. A digital predistortion module is used by the transmitter to digitally process the input signal to generate a predistortion signal that models an inverse of the non-linearity of the power amplifier. In addition, means, located between the filter and the power amplifier, for combining the predistortion signal with the main signal to generate a combined signal, and for providing the combined signal to the power amplifier, is located within the transmitter.
