This article reviews the history and concepts behind the linearizers in use today.
Predistortion linearization is by far the most widely used form of linearization and is most …

In this paper, we provide a survey on techniques to improve the spectrum and energy
efficiency of wireless communication systems. Recognizing the fact that power amplifier (PA) …

This paper presents the design and implementation of the first in-band full duplex WiFi-PHY
based MIMO radios that practically achieve the theoretical doubling of throughput. Our …

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 …

This paper addresses the modeling and cancellation of self-interference in full-duplex direct-
conversion radio transceivers, operating under practical imperfect radio frequency (RF) …

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 …

Deep learning-based fingerprinting techniques have recently emerged as potential enablers
of various wireless applications. However, their resiliency to time, location, and/or …

In this paper, we propose a beam-oriented digital predistortion (BO-DPD) technique for
power amplifiers (PAs) in hybrid beamforming massive multiple-input multiple-output (MIMO) …

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 …
