Increasing Cellular Network Energy Efficiency for Railway Corridors

Andreas Peter Burg, Adrian Schumacher, Ruben Merz

Modern trains act as Faraday cages making it challenging to provide high cellular data capacities to passengers. A solution is the deployment of linear cells along railway tracks, forming a cellular corridor. To provide a sufficiently high data capacity, m ...

Physical Layer Aspects of LoRa and Full-Duplex Wireless Transceivers

Orion Afisiadis

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 ...

Ultra Low Power FM-UWB Transceiver for High-Density Wireless Sensor Networks

Vladimir Kopta

The WiseSkin project aims to provide a non-invasive solution for restoration of a natural sense of touch to persons using prosthetic limbs. By embedding sensor nodes into the silicone coating of the prosthesis, which acts as a sensory skin, WiseSkin target ...

Multi-Terabit/s Transmission Using Chip-Scale Frequency Comb Sources

Tobias Kippenberg, Victor Brasch, Tobias Herr

Chip-scale frequency comb sources are likely to become key elements of future terabit/s optical transceivers. We investigate and demonstrate the viability of different comb generation schemes for transmission at multiterabit/s data rates. ...

High Symbol Rate Coherent Optical Transmission Systems: 80 and 107 Gbaud

Rüdiger Urbanke, Luis Salamanca Miño

We demonstrate high speed optical transmission systems using digital coherent detection at all-electronically multiplexed symbol rates of 80 and 107 Gbaud. At 107 Gbaud, we demonstrate a single-carrier polarization division multiplexed quadrature phase shi ...

Calibration of the GNSS Signal Amplitudes in the Interference Pattern Technique for Altimetry

Pierre-André Farine, Cyril Botteron, Miguel Angel Ribot Sanfelix, Mohammed Benjelloun

Global Navigation Satellite Systems signals can be used in bi-static radar systems in order to get altimetric measurements. With a single classic GNSS ground-based receiver processing the combination of the signals coming directly and after one reflection ...

Method for estimating and correcting a drift between clocks of receiving transceiver and a corresponding emitting transceiver, and receive for implementing said method

Jean-Yves Le Boudec, Ruben Merz, Manuel Flury

Method for estimating and correcting a frequency offset between a local clock of a receiving transceiver and a remote clock of an emitting transceiver comprises receiving by said receiving transceiver, a signal emitted by the emitting transceiver, said sig ...

Design of a 2.4 Ghz BAW-Based CMOS Transmitter

Matteo Contaldo

In recent years, bulk acoustic wave resonators (BAW) in combination with RF circuits have shown a big potential in achieving the low-power consumption and miniaturization level required to address wireless sensor nodes (WSN) applications. A lot of work has ...

Wireless Voltage Regulation for Passive Transponders Using an IF to Communicate

Catherine Dehollain, Michel Declercq, Nicolas Pillin

This paper presents a novel architecture for wireless communication systems made up of a base station and a remotely powered transponder. The architecture enables the base station to perform wireless voltage regulation (WVR) of the rectifier's output volta ...
