Nonlinear problems have drawn great interest and extensive attention from engineers,
physicists and mathematicians and many other scientists because most real systems are …

Envelope tracking (ET) is by now a well-established technique that improves the efficiency of
microwave power amplifiers (PAs) compared to what can be obtained with conventional …

In this paper, the problem of resource management is studied for a network of wireless
virtual reality (VR) users communicating over small cell networks (SCNs). In order to capture …

The RF PA, as one of the most essential components in any wireless system, suffers from
inherent nonlinearities. The output of a PA must comply with the linearity requirement …

The continuously increasing demand for wide bandwidth creates great difficulties in
employing digital predistortion (DPD) for radio frequency (RF) power amplifiers (PAs) in …

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 …

The work has presented duobinary modulation and predistortion techniques for the radio
over fiber system enhancement for achieving security level. Duobinary modulation …

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 proposes a design approach for a broadband and high-efficiency continuous
inverse Class-F (CCF-1) power amplifier (PA) based on a modified elliptic low-pass filtering …

This paper presents a high-efficiency gallium nitride Doherty power amplifier (DPA) using an
integrated compensating reactance (CR) for broadband operation. With an additional …
