A Low-Complexity LoRa Synchronization Algorithm Robust to Sampling Time Offsets

Orion Afisiadis, Mathieu Pierre Xhonneux

LoRaWAN is nowadays one of the most popular protocols for low-power Internet of Things communications. Although its physical layer, namely LoRa, has been thoroughly studied in the literature, aspects related to the synchronization of LoRa receivers have re ...

Enhancing the Reliability of Dense LoRaWAN Networks With Multi-User Receivers

Andreas Peter Burg, Joachim Tobias Tapparel, Mathieu Pierre Xhonneux

LoRaWAN is a low-power wireless technology that provides long-range connectivity to battery-powered Internet of Things (IoT) devices. To minimize the energy consumption of the IoT nodes, LoRaWAN networks use for the uplink a pure non-slotted ALOHA multiple ...

[POSTER] Double Reality: Shifting the Gaze Between the Physical Object and Its Digital Representation

Pierre Dillenbourg, Lorenzo Lucignano

We present an eye-tracking study centered on the shift of focus from digital to physical layer in case of a handheld magic-lens system. In particular, we investigate which variables might affect the occurrence of such events. The experiment involved 35 par ...

Cross-Layer Energy-Efficiency Optimization of Packet Based Wireless MIMO Communication Systems

Andreas Peter Burg, Georgios Karakonstantis, Carl Christian Sten Dominic Senning

Energy in today's short-range wireless communication is mostly spent on the analog-and digital hardware rather than on radiated power. Hence, purely information-theoretic considerations fail to achieve the lowest energy per information bit and the optimiza ...

Energy Efficient VLSI Circuits for MIMO-WLAN

Carl Christian Sten Dominic Senning

Mobile communication - anytime, anywhere access to data and communication services - has been continuously increasing since the operation of the first wireless communication link by Guglielmo Marconi. The demand for higher data rates, despite the limited b ...

On Secure and Precise IR-UWB Ranging

Jean-Yves Le Boudec, Jean-Pierre Hubaux, Panagiotis Papadimitratos, Marcin Poturalski, Manuel Flury

To provide high ranging precision in multipath environments, a ranging protocol should find the first arriving path, rather than the strongest path. We demonstrate a new attack vector that disrupts such precise Time-of-Arrival (ToA) estimation, and allows ...

Synchronization for Impulse-Radio UWB With Energy-Detection and Multi-User Interference: Algorithms and Application to IEEE 802.15.4a

Jean-Yves Le Boudec, Ruben Merz, Manuel Flury

Energy-detection (ED) receivers can take advantage of the ranging and multipath resistance capabilities of impulse-radio ultra-wideband (IR-UWB) physical layers at a much lower complexity than coherent receivers. However, ED receivers are extremely vulnera ...

A Discrete-Components Impulse-Radio Ultrawide-Band (IR-UWB) Transmitter

Catherine Dehollain, Edmund James Colli-Vignarelli

We describe an impulse-radio ultra-wideband (IR-UWB) transmitter made with off-the-shelf discrete components. It was initially designed to be used in a UWB testbed for measurement and algorithm validation purposes. There already exist several versions of a ...
