The realm of sustainable technologies and metamaterials represents a vibrant field of
inquiry, and, upon closer examination, a fascinating correlation emerges. Metamaterials …

Every new generation of mobile systems should provide higher capacity, serve more users,
be more energy efficient, and have lower cost. Radio-access hardware constitutes a major …

In this article, a thorough overview of behavioral modeling and predistortion of dynamic
nonlinearities in RF PAs and transmitters was presented. The sensitivity of the DUT behavior …

A new representation of the Volterra series is proposed, which is derived from a previously
introduced modified Volterra series, but adapted to the discrete time domain and …

A comparative study of state-of-the-art behavioral models for microwave power amplifiers
(PAs) is presented in this paper. After establishing a proper definition for accuracy and …

A comparative study of nonlinear behavioral models with memory for radio-frequency power
amplifier (PAs) is presented. The models are static polynomial, parallel Hammerstein (PH) …

In this paper, a novel two hidden layers artificial neural network (2HLANN) model is
proposed to predict the dynamic nonlinear behavior of wideband RF power amplifiers (PAs) …

A new behavioral model for digital predistortion of radio frequency (RF) power amplifiers
(PAs) is proposed in this paper. It is derived from a modified form of the canonical piecewise …

This paper presents an overview of recently-developed, simplified Volterra series based,
behavioral modeling approaches for radio frequency and microwave power amplifiers …

In this paper, we propose a technique for comprehensive analysis of nonlinear and dynamic
characteristics of multi-antenna transmitters (TXs). The analysis technique is enabled by the …
