Density Estimation Models for Strong Nonlinearities in RF Power Amplifiers
2014 (English)In: 2014 Asia-Pacific Microwave Conference Proceedings, APMC 2014, 2014, 116-118 p.Conference paper (Refereed)
The paper presents a method for modeling strongnonlinear effects in power amplifiers based on the principlesof density estimation. The static nonlinear transfer function isobtained by averaging measured data. The performance obtainedwith density estimation is similar to the one using high ordernonlinear static polynomial models. The benefit of consideredmethod over the ones using polynomial models is that the formerestimates blindly the structure of the transfer function and doesnot suffer from numerical instabilities.
