Aerial networks represent a complementary technology for the provision of fifth-generation
(5G) wireless communication services via high-and low-altitude platforms (HAPs/LAPs) or …

High-altitude platforms (HAPs) are one of the most promising alternative infrastructures for
realizing next-generation high-data-rate wireless networks. This paper investigates the …

As the development of next-generation wireless communication systems envisages the
synergetic integration of heterogeneous terrestrial and aerospace networks, high-altitude …

In this work we propose a model (invalidation approach to gait recognition, using a system
that tries to discriminate specific activities of people. The recognition process departs from …

In this paper we present a geometric multipath propagation model for a microcell mobile
environment. The proposed model provides the statistics for the direction-of-arrival (DOA) of …

Using out-of-band (OOB) side-information has recently been shown to accelerate beam
selection in single-user millimeter wave (mmWave) massive MIMO (m-MIMO) …

Three-dimensional (3D) multi-input-multi-output (MIMO) is one of the enabling technologies
for next-generation mobile communication. As the elevation angle in the 3D MIMO channel …

It is shown that the use of chaos shift keying (CSK) with a transmit diversity technique such
as beamforming and space-time coding can provide a secure communication link with …

A geometric scattering model that predicts the actual measured probability density functions
(pdf's) for the direction-of-arrival (DOA) and time-of-arrival (TOA) is highly desirable …

High altitude platforms (HAPs) have been designated as an alternative wireless
infrastructure for facilitating next generation high-speed mobile communications services …
