Journal ArticleDOI
A robust digital baseband predistorter constructed using memory polynomials
Lei Ding,Guotong Zhou,Dennis R. Morgan,Zhengxiang Ma,J.S. Kenney,Jaehyeong Kim,C.R. Giardina +6 more
TL;DR: A memory polynomial model for the predistorter is proposed and implemented using an indirect learning architecture and linearization performance is demonstrated on a three-carrier WCDMA signal.
Journal ArticleDOI
Behavioral modeling of nonlinear RF power amplifiers considering memory effects
Hyunchul Ku,J.S. Kenney +1 more
TL;DR: In this article, the authors proposed a behavioral model to treat memory effects in nonlinear power amplifiers (PAs) by augmenting the memory polynomial model with a sparse delay tap structure that reduces the parameter space required for accurate model identification.
Journal ArticleDOI
Quantifying memory effects in RF power amplifiers
TL;DR: By using a system-level behavioral model for RF power amplifiers (PAs), which exhibit memory effects, that is based on the parallel Wiener system, it is found that more accurate adjacent-channel power-ratio levels may be predicted for high PAS close to the carrier frequency.
EVM Calculation for Broadband Modulated Signals
Michael D. McKinley,Kate A. Remley,Maciej Tomasz Myslinski,J.S. Kenney,Dominique Schreurs,Bart Nauwelaers +5 more
TL;DR: A normalization that facilitates calculation of error vector magnitude (EVM) from measurements is presented and the definition of EVM for a common industry standard is derived from a more basic equation.
Proceedings ArticleDOI
Memory polynomial predistorter based on the indirect learning architecture
Lei Ding,Guotong Zhou,Dennis R. Morgan,Zhengxiang Ma,J.S. Kenney,Jaehyeong Kim,C.R. Giardina +6 more
TL;DR: This paper proposes a memory polynomial model for the predistorter and implements it using an indirect learning architecture, and linearization performance is demonstrated on a 3-carrier UMTS signal.
