Modeling and Benchmarking Ultra-Wideband Localization for Mobile Robots

Alcherio Martinoli, Catherine Dehollain, Alexander Bahr, Edmund James Colli-Vignarelli

Ultra-Wideband Impulse Radio (UWB-IR) is a technology that has great potential to solve numerous mobile robotic and asset tracking problems in GPS-denied environments. Our goal is to help software and hardware designers in improving the state-of-the-art in ...

Design 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

Edmund James Colli-Vignarelli

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 ...

IR-UWB transmitter

Jean-Yves Le Boudec, Catherine Dehollain, Edmund James Colli-Vignarelli

A generator of very short pulses where a cascade of inverters of arbitrary length characterized in that said inverters are adapted to produce pulses on their power supply line instead of their usual output. ...

Toward the Deployment of an Ultra-Wideband Localization Test Bed

Alcherio Martinoli, Catherine Dehollain, Alexander Bahr, Edmund James Colli-Vignarelli

The design, development, and deployment of Ultra-Wideband (UWB) localization systems involves digital and Radio-Frequency (RF) hardware, embedded software, localization algorithms, security and reliability aspects, electromagnetics, and others. Design and ...

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 ...

A discrete-components impulse-radio UWB Low-Noise Amplifier with voltage controlled-gain

Catherine Dehollain, Edmund James Colli-Vignarelli

We describe an Ultra-Wide Band Low-Noise Amplifier (LNA) with a variable gain that works in the 4.0 GHz to 4.5 GHz frequency range and is made with off-the-shelf discrete components. This LNA has a 30 dB variable gain and a noise figure of 2.2 dB. It was i ...
