چکیده
In this paper, we present a novel predistortion method based on Fuzzy Wavelet Neural Networks (FWNN) to linearize the High Power Amplifier (HPA) for WiMAX (Worldwide interoperability for Microwave Access). To analyze and evaluate the proposal, we are considered the model of Traveling Wave Tube Amplifiers (TWTA), both memoryless and with memory. The simulation results show that the proposed scheme provide a satisfactory performances in term of Bit Error Rate (BER) and EVM criteria.

Multicarrier Power Amplifier Linearization Based on Artificial Intelligent Methods
This paper presents two new intelligent methods to linearize the Multi-Carrier Power Amplifiers (MCPA). One of the them is based on the Neuro-Fuzzy controller while the other uses two small neural networks as a polar predistorter. Neuro-Fuzzy controllers are not model based, and hence, have ability to control the nonlinear systems with undetermined parameters. Both methods are adaptive, low com...
متن کاملDigital Pre-Distorter Based On A Box Oriented Memory Polynomial Model and Optimized By Tabu Search Algorithm for Wimax Radio Frequency Power Amplifier
Digital predistortion (DPD) technique is widely used to linearize a radio frequency power amplifier (PA). It is the fastest and cost effective digital processing technique to moderate the distortions in PA caused by nonlinearity and memory effects. Digital predistorter is inverse of the PA, so the design of a digital predistorter requires the accurate identification of PA’s behavior. This paper...

متن کاملFPGA Implementation of a Hammerstein Based Digital Predistorter for Linearizing RF Power Amplifiers with Memory Effects
Power amplifiers (PAs) are inherently nonlinear elements and digital predistortion is a highly cost-effective approach to linearize them. Although most existing architectures assume that the PA has a memoryless nonlinearity, memory effects of the PAs in many applications ,such as wideband code-division multiple access (WCDMA) or orthogonal frequency-division multiplexing (OFDM), can no longer b...
