—The indirect learning architecture (ILA) is the most used methodology for the identification of Digital Pre-distorter (DPD) functions for nonlinear systems, particularly for high power amplifiers. The ILA principle works in black box modeling relying on the inversion of input and output signals of the nonlinear system, such that the inverse is estimated.(More)
—A non-parametric technique to model the behavior of power amplifiers is presented. The proposed technique relies on the principles of density estimation using the kernel method and it is suited for the application of power amplifier modeling. The proposed methodology transforms the input domain to an orthogonal memory domain. In such a domain,(More)
—In this paper, a synthetic vector network analyzing measurement system is presented. The system is based on a hardware setup, including a signal generator and a vector signal analyzer, with the vector network analyzing functionality implemented in the software. The measurements of the proposed system demonstrated comparable performance in terms of accuracy(More)
