In this paper, FPGA implementation of augmented Hammerstein predistorters for linearizing wideband RF power amplifiers with memory effects is presented. The augmented Hammerstein nonlinear model based predistorter is briefly introduced. The implementation method of the augmented Hammerstein predistortion on FPGA is described in details. The experimental platform based on Agilent vector signal generators...
In this paper, the dependence of the static nonlinear properties of the wideband RF power amplifiers on the applied signals has been discussed to illustrate the necessity to extract the static nonlinear properties in real time while applying the real modulated signal. A novel dynamic exponential weighted moving average method is proposed to extract the static nonlinear properties of the wideband RF...
In this paper, a spectral method based on the memoryless predistortion technique is presented to identify accurately the memory effects of wideband RF power amplifiers stimulated by practical modulated signals. According to this new definition of the memory effects, a novel metric to measure quantitatively the memory effects in wideband power amplifiers is proposed. With the proposed memory effect...
