Precoding for High-Throughput Satellite Communication Systems: A Survey
With the expanding demand for high data rates and extensive coverage, high throughput satellite (HTS) communication systems are emerging as a key technology for future communication generations. However, current frequency bands are increasingly congested. ...
Ieee-Inst Electrical Electronics Engineers Inc2024A 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 ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022Enhancing 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 ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2021Physical Layer Aspects of LoRa and Full-Duplex Wireless Transceivers
Wireless communications are currently faced with two main challenges. The first challenge stems from the enormous number of Internet of Things (IoT) devices that transmit very small amounts of data. The second challenge is the need for ever-increasing data ...
EPFL2020Lora Digital Receiver Analysis And Implementation
Andreas Peter Burg, Orion Afisiadis, Reza Ghanaatian Jahromi, Matthieu Cotting
Low power wide area network technologies (LPWANs) are attracting attention because they fulfill the need for long range low power communication for the Internet of Things. LoRa is one of the proprietary LPWAN physical layer (PHY) technologies, which provid ...
IEEE2019An Approximate Zero IF FM-UWB Receiver for High Density Wireless Sensor Networks
A low-power frequency modulated-ultra-wideband (FM-UWB) receiver for short-range communications, capable of simultaneously demodulating multiple FM-UWB signals located at the same frequency, is presented in this paper. The proposed receiver utilizes an "ap ...
Institute of Electrical and Electronics Engineers2017Energy 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 ...
EPFL2014On 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 ...
Institute of Electrical and Electronics Engineers2012Design of a Discrete-Component Impulse-Radio Ultra Wide-Band (IR-UWB) Testbed and Design of a very Low-Power IR-UWB Transmitter in CMOS Technology
This work presents, in a first part, a testbed for Impulse-Radio Ultra-Wideband (IR-UWB) communication for validating the possibility to do such radio communications. The UWB radio is a radio technique that consists to send extremely short impulses (few na ...
