This paper expounds a complexity-reduced generalized memory polynomial (CR-GMP) model for multi-band power amplifier (PA) digital predistortion (DPD). First, PA block diagrams characterizing the behavior of PAs under multi-band stimulus are proposed.

In this paper, a novel two hidden layers artificial neural network (2HLANN) model is proposed to predict the dynamic nonlinear behavior of wideband RF power amplifiers (PAs). Starting with a generic low-pass equivalent circuit of the PA, several circ

In this paper, a novel extended Hammerstein model is presented to accurately mimic the dynamic nonlinearity of wideband RF power amplifiers (RFPAs). Starting with a conventional Hammerstein model scheme, which fails to predict the behavior of the RFP

A new approach for modeling wideband power amplifiers (PAs) using a reduced transmitter observation receiver (TOR) bandwidth is proposed. The general sampling theorem (GST) was used to lower the bandwidth requirement of the TOR. This approach highlig

This paper expounds on the pruning of Volterra series used to linearize power amplifiers (PAs) exhibiting memory effects. This pruning approach starts with the identification of the minimum set of dominant kernels needed in the Volterra series modeli

In this paper, a new formulation of the polynomial based digital predistortion (DPD) is proposed. This formulation reduces the amount of hardware resources (memory and logic) required for the implementation while maintaining adequate precision. Addit
