Fifth-generation (5G) cellular networks will almost certainly operate in the high-bandwidth,
underutilized millimeter-wave (mmWave) frequency spectrum, which offers the potentiality of …

Purpose Optimization involves changing the input parameters of a process that is
experimented with different conditions to obtain the maximum or minimum result. Increasing …

This paper presents our experience in designing, implementing, testing, and applying a
general-purpose antenna extension solution with commodity Wi-Fi. The proposed solution …

In this paper, circular and hexagonal array geometries for smart antenna applications are
compared. Uniform circular (UCA) and hexagonal arrays (UHA) with 18 half-wave dipole …

Future telecommunications aim to be ubiquitous and efficient, as widely deployed
connectivity will allow for a variety of edge/fog based services. Challenges are numerous …

We present a MUSIC-based Direction of Arrival (DOA) estimation strategy using small
antenna arrays, via employing deep learning for reconstructing the signals of a virtual large …

Designing beampatterns with constant beamwidth over a wide range of frequencies is useful
in many applications in speech, radar, sonar and communication. In this paper, we design …

This article investigates the achievable spectral efficiency (SE) of millimeter wave massive
multiple-input multiple-output systems with three different array topologies deployed at the …

We consider the design of a uniform circular array (UCA) system under array misalignment
over line-of-sight (LoS) channels. UCAs have been considered as useful array structures …

A blind Direction-of-Arrivals (DOAs) estimate of narrowband signals for Acoustic Vector-
Sensor (AVS) arrays is proposed. Building upon the special structure of the signal measured …
