The histrionic growth of mobile subscribers, disruptive ecosystems such as IoT-based
applications, and astounding channel capacity requirements to connect trillions of devices …

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 investigates digital predistortion (DPD) linearization of hybrid beamforming large-
scale antenna transmitters. We propose a novel DPD processing and learning technique for …

In this article, we describe a novel framework for digital predistortion (DPD)-based
linearization of strongly nonlinear millimeter-wave active antenna arrays. Specifically, we …

Time-division duplex (TDD) and frequency-division duplex (FDD) are mainly used in
commercial new radio (NR) deployments, where the time-or frequency-domain resources …

To accommodate growing user demand for faster data rates and extensive connectivity,
modern wireless communication systems must evolve to support a sharply increasing …

The distortion from massive multiple-input multiple-output base stations with nonlinear
amplifiers is studied and its radiation pattern is derived. The distortion is analyzed both in …

We study the spectral efficiency (SE) of a mixed-analog-to-digital converter (ADC) massive
multiple-input multiple-output (MIMO) system in which K single-antenna users communicate …

Efficient mitigation of power amplifier (PA) nonlinear distortion in multi-user hybrid precoding
based broadband mmWave systems is an open research problem. In this article, we carry …

The power consumption of digital-to-analog converters (DACs) constitutes a significant
proportion of the total power consumption in a massive multiuser multiple-input multiple …
