Abstract
Due to the development of wireless communication systems, the linearity requirement of power amplifiers (PAs) is very stringent. A new concept was proposed to model a predistorter directly without modeling a PA firstly. The algorithm can not only improve the linearity of amplifier, but also adjust the gain of PAs dependently. Based on this algorithm, the behavioral model and structure of the predistorter are also introduced. Linearization performance is demonstrated on a WCDMA signal.
