Abstract :
Power amplifier is essential component in communication systems and it´s inherently nonlinear. This essay mainly investigate a based on Hammerstein predistorter, a memory polynomial predistorter. The Hammerstein predistorter is designed specifically for power amplifiers that can be modeled as a Wiener system. The memory polynomial predistorter can correct both the nonlinear distortions and the linear frequency response that may exist in the power amplifier.
