In this paper, we analyze the challenges faced by multipair massive Multiple-input-multiple-
output (MIMO) relay channels in 5G wireless communication systems, where high path loss …

Satisfying the exponential data growth is one of the main challenges for the design of future
wireless networks. Given the abundant spectrum availability at millimeter-wave bands …

This paper presents a measurement-based analysis of wideband 39 GHz millimeter wave
(mm-wave) dual-polarized propagation channel under the impact of foliage presence …

Polarization selectivity has a great impact on multiple-input–multiple-output (MIMO) relay
channels. In this letter, the channel capacity of MIMO relay channels is analyzed, revealing …

We begin by investigating relationships between two forms of Hilbert–Schmidt two-rebit and
two-qubit “separability functions”—those recently advanced by Lovas and Andai (J Phys A …

The quality of people's lives can be improved through the use of Smart (wireless) Solutions,
namely for medical, daily life and occupational purposes. However, these advantages may …

In this paper, we parameterize an excess loss-based multipath component (MPC) cross-
polarization ratio (XPR) model in indoor and outdoor environments for above-5-GHz …

This paper discusses a polarimetric measurement campaign conducted in two distinct
environments, with data collected at the Federal University of Minas Gerais (UFMG) in Brazil …

Recently, a measurement campaign for characterizing time-variant radio channels in city-
canyon environments was conducted along a 2-km-long pedestrian shopping street in …

Multiple-input multiple-output (MIMO) systems capacity is highly influenced by the
correlation between antennas, and the high correlation will result in a low capacity …
