info:eu-repo/semantics/article,
In the advent of becoming reality, the era of autonomous vehicles is closer than ever, and with it, the need for faster and reliable wireless connections. The propagation channel determines the performance limits of wireless ...
Towards sub-meter level UWB indoor localization using body wearable sensors
(IEEE, 2020)
info:eu-repo/semantics/article,
Thanks to its ability to provide sub-meter level positioning accuracy, Ultrawideband (UWB) has found wide use in several wireless body area network (WBAN) applications such as ambient assisted living, remote patient ...
An enhanced approach to virtually increase quasi-stationarity regions within geometric channel models for vehicular communications
(IEEE, 2023)
Artículo / Artikulua,
Vehicular communication channels are intrinsically
non-stationary, as they present high mobility and abundant dynamic
scatterers. Quasi-stationary regions can assess the degree
of non-stationarity within a determined ...
Design of high gain base station antenna array for mm-wave cellular communication systems
(Springer Nature, 2023)
Artículo / Artikulua,
Millimeter wave (mm-Wave) wireless communication systems require high gain antennas to overcome path loss effects and thereby enhance system coverage. This paper presents the design and analysis of an antenna array for ...
Review on unmanned aerial vehicle assisted sensor node localization in wireless networks: soft computing approaches
(IEEE, 2022)
Artículo / Artikulua,
Node positioning or localization is a critical requisite for numerous position-based applications of wireless sensor network (WSN). Localization using the unmanned aerial vehicle (UAV) is preferred over localization using ...
High gain/bandwidth off-chip antenna loaded with metamaterial unit-cell impedance matching circuit for sub-terahertz near-field electronic systems
(Springer, 2022)
Artículo / Artikulua,
An innovative of-chip antenna (OCA) is presented that exhibits high gain and efciency performance
at the terahertz (THz) band and has a wide operational bandwidth. The proposed OCA is implemented
on stacked silicon layers ...
