An efficient digital Volterrapredistorter ispresented to compensatefor nonlinear distortion with memory induced by a broadband RF high power amplifier. The proposed approach is based on mixeddomain Volterra system estimation and optimalpth-order

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 spec

The digital baseband predistorter is an effective technique to compensate for the nonlinearity of power amplifiers (PAs) with memory effects. However, most available adaptive predistorters based on direct learning architectures suffer from slow c

The application of digital predistortion in base-band signal is an extended method of amplifier linearization to reduce the Adjacent Channel Interference (ACI) in those systems in which a varying envelope modulation scheme is used. This paper
