Adaptive Digital Predistortion with Applications for LMDS Systems
… are the primary causes of the limited distance. Adaptive digital predistortion is presented as a method of increasing effective transmitter power. A background on LMDS link design, non-linear amplification, and predistortion is presented to assist the reader. A developed simulation uses AM-AM and …

New architecture for RF power amplifier linearization
… solutions : two-point architecture and adaptive digital predistortion using a [delta sigma] modulator for automatic inversion of power amplifier nonlinearity. Two-point architecture can be seen as a solution that extends the linearization bandwidth of the traditional feedback …

Design and Linearization of Energy Efficiency Power Amplifier in Nonlinear OFDM Transmitter for LTE-5G Applications. Simulation and measurements of energy efficiency power amplifier in the presence of nonlinear OFDM transmitter system and digital predistortion based on Hammerstein-Wiener method
… memory cancellation. Moreover, an enhanced adaptive Wiener model is proposed to explore the nonlinear memory effect in the system. The proposed approach is able to balance between convergence speed and high-level accuracy when compared with behavioural modelling algorithms that are more …
