Indoor Positioning System Based on Global Positioning System Signals with Down- and Up-Converters in 433 MHz ISM Band

Amir Mohsen Ahmadi Najafabadi, Abdulkadir Uzun

In this paper, an indoor positioning system using Global Positioning System (GPS) signals in the 433 MHz Industrial Scientific Medical (ISM) band is proposed, and an experimental demonstration of how the proposed system operates under both line-of-sight an ...

Advanced Machine Learning Techniques for Self-Interference Cancellation in Full-Duplex Radios

Andreas Peter Burg, Andreas Toftegaard Kristensen

In-band full-duplex systems allow for more efficient use of temporal and spectral resources by transmitting and receiving information at the same time and on the same frequency. However, this creates a strong self-interference signal at the receiver, makin ...

Non-Linear Digital Self-Interference Cancellation for In-Band Full-Duplex Radios Using Neural Networks

Alexios Konstantinos Balatsoukas Stimming

Full-duplex systems require very strong self-interference cancellation in order to operate correctly and a significant part of the self-interference signal is due to non-linear effects created by various transceiver impairments. As such, linear cancellatio ...

Wideband Omnidirectional Planar Antenna with Vertical Polarization

Juan Ramon Mosig, Lei Wang

In this paper we propose a circular leaky wave-antenna with omnidirectional radiation in the H-plane. The design utilizes double-layered strips to create an end-fire antenna. A linear tapering of the stripes in the design endows the antenna with a 27% impe ...

Modulated scattering technique in the terahertz domain enabled by current actuated vanadium dioxide switches

Juan Ramon Mosig, Mihai Adrian Ionescu, Anja Skrivervik, Michele Tamagnone, Wolfgang Amadeus Vitale, Santiago Capdevila Cascante

The modulated scattering technique is based on the use of reconfigurable electromagnetic scatterers, structures able to scatter and modulate an impinging electromagnetic field in function of a control signal. The modulated scattering technique is used in a ...

Multi-test Detection and Protection Algorithm Against Spoofing Attacks on GNSS Receivers

Pierre-André Farine, Cyril Botteron, Aleksandar Jovanovic

The vulnerability against interference, spoofing, and jamming of GNSS receivers is considered nowadays a major security concern. This security threat is exacerbated with the existing market availability of GPS jamming and spoofing equipment sold at reasona ...

An overview of W-BAN antennas designed at LEMA

Anja Skrivervik

W-BAN applications have been around since a long time, but have been experiencing a tremendous growth during the last decades. This results in the need of dedicated antennas, which are designed and optimized taking into account their lossy surroundings. De ...

Glass transition associated with the jamming of vibrated granular matter

Daniele Mari, Gérard Gremaud, Alessandro Luigi Sellerio

We investigate a vibrated granular system composed of millimeter-size glass beads. When the system is submitted to a perturbation with decreasing intensity, below the fluidization limit, it evolves in a way similar to glass-forming liquids until it reaches ...

Measuring school contact networks using wireless sensor technology

Marcel Salathé

Interaction networks shaped by social processes constitute the substrate on which various phenomena of interest to human biology occur, for example, epidemics, diffusion of health information, and the exertion of social influence related to health. Underst ...
