In this article, we review the key concepts and the progress in the design of physical-layer
aspects of in-band full-duplex (IBFD) communications. One of the fundamental challenges in …

Power amplifiers (PAs) are inherently nonlinear devices and are used in virtually all
communications systems. Digital baseband predistortion is a highly cost-effective way to …

The polynomial model is commonly used in power amplifier (PA) modeling and predistorter
design. However, the conventional polynomial model exhibits numerical instabilities when …

In a visible light communication (VLC) system, the light-emitting diode (LED) is the major
source of nonlinearity. The nonlinear effects in the VLC system are different from the …

In this paper, an augmented lookup-table-based Hammerstein predistorter is proposed for
the first time in order to further improve the pre-correction capability of the traditional …

Digital predistortion is one of the most cost effective ways among all linearization
techniques. However, most of the existing designs treat the power amplifier as a memoryless …

Power amplifiers (PAs) are inherently nonlinear devices and are used in virtually all
communications systems. Digital baseband predistortion is a highly cost effective way to …

Least squares (LS) estimation is widely used in model extraction of digital predistortion for
RF power amplifiers. In order to reduce computational complexity and implementation cost, it …

nonlinear distortion introduced filed on May 6, 2004, OW Pat No. 7,342,976, which is by …

This paper presents a new method of digital adaptive predistortion for linearization of power
amplifiers (PAs) exhibiting memory effects. The predistorter (PD) device consists of a lookup …
