Abstract

In a wireless communication system, a predistorter is often employed to alleviate nonlinear distortions due to operating a power amplifier near saturation, thereby improving the system performance and reducing the interference to adjacent channels. In this paper, we investigate the performance of a new digital predistorter. A 16-QAM communication system is used as an example to show that the predistorter indeed eliminates the nonlinear distortion, and can greatly improve the performance of the communication system.
