Piecewise Polynomial Predistorter for Power Amplifier
ABSTRACT In this paper, we propose a novel predistortion scheme, in which multiple polynomials are used to predistort the input signal instead of a single one, by dividing input signal range into several regions. The recursive least squares (RLS) algorithm is used for optimizing process to minimize the errors between input of predistorter and the output of amplifier. From the simulation results...
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...
متن کاملEfficient Baseband Digital Predistorter Using Lut for Power Amplifier (PA) with Memory Effect
Modern communications systems will have to integrate multiple radio technologies to support a large number of wireless standards (WLAN, WPAN...). This system should operate with third generation (3G) air interface standards, where non constant envelope modulation formats (MQAM, OFDM...) are required. The amplification of a modulated signal with large variation of envelope introduces distortions...
متن کاملLinearization of Time-varying High-power Amplifier using Adaptive Digital Predistorter
An efficient adaptive predistortion technique is proposed to compensate linear or nonlinear distortions caused by a high-power amplifier (HPA) with memory in OFDM communication systems. Previous adaptive predistortion techniques, based on Volterra series, are not suitable for real-time implementation due to high computational burden and slow convergence rate. In the proposed approach, the memor...
متن کاملHigh Power Amplifier Predistorter Based on Fuzzy Wavelet Neural Networks for WiMAX Signals
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 sche...
