5G Terrestrial Networks: Mobility and Coverage—Solution in Three Dimensions

open access: yesIEEE Access, 2017
The next generation of wireless communications, which is proposed to operate in the mmWave region of the electromagnetic spectrum, offers the potential of high-data rate and increased coverage in response to a rapid growth of mobile data traffic ...

Polarization Combining and Equalization in 5G Mobile-to-Mobile Systems

open access: yesIEEE Access, 2022
This article develops maximum likelihood (ML) detection for post-FFT processing of dual-polarized antenna outputs with a cyclic-prefix OFDM (CP-OFDM) waveform for a frequency selective multipath fading in a 5G mobile-to-mobile setting.

Polarization Diversity in Ring Topology Networks [PDF]

open access: yes2016 IEEE 84th Vehicular Technology Conference (VTC-Fall), 2016
Polarization diversity is generally achieved by using two orthogonal polarizations on the same link, which enables to double the available bandwidth. In this paper, we study the possibility to connect the nodes of a line-of- sight ring topology network with one single channel for all the links, with the condition that the polarization of any link is ...

Polarity and the diversity of growth mechanisms in bacteria [PDF]

open access: yesSeminars in Cell & Developmental Biology, 2011
Bacterial cell growth is a complex process consisting of two distinct phases: cell elongation and septum formation prior to cell division. Although bacteria have evolved several different mechanisms for cell growth, it is clear that tight spatial and temporal regulation of peptidoglycan synthesis is a common theme.

Adaptive Polarization Diversity and Directivity Mode Selection in RIS-Aided Systems

open access: yesIEEE Access
This paper proposes an adaptive architecture for Reconfigurable Intelligent Surface (RIS)-assisted wireless communication, enhancing system performance by dynamically switching between polarization diversity and directivity modes. The RIS is divided into

Polarization-independent tunable optical filter with variable bandwidth based on silicon-on-insulator waveguides

open access: yesNanophotonics, 2018
We present a polarization-independent tunable optical filter with variable bandwidth based on silicon-on-insulator (SOI) waveguides. The polarization-independent operation is achieved through the use of a polarization splitter-rotator and a polarization ...

A Time Modulated Array With Polarization Diversity Capability

open access: yesIEEE Access, 2021
The Time Modulated Array (TMA) provides multiple radiation beams at different frequencies, by turning the radiating elements on and off. In this paper, we propose to add polarization diversity to a wireless communication link by leveraging the ...
