This paper describes a receiver system design for impulse-radio ultra-wideband (IR-UWB) that operates at two carrier frequencies-3.494 and 3.993 GHz-with a 10-Mbps data rate. To reduce the power consumption of the front-end amplifiers, a super-regenerative ...
We propose an algorithm (SCS-FRI) to estimate multipath channels with Sparse Common Support (SCS) based on Finite Rate of Inno- vation (FRI) sampling. In this setup, theoretical lower-bounds are derived, and simulation in a Rayleigh fading environment show ...

Communication systems have played a key role in changing our lives as such systems help to access remote data and to transfer it to the end user when requested. Intelligent nodes, which can process and transmit information placed in a given environment can ...
In this thesis we study Impulse-Radio Ultra-Wide Band (IR-UWB), a physical layer radio technology offering many features that make it a promising choice for future short-range wireless networks. The challenges in such networks are many, ranging from the co ...
Personal Digital Assistants (PDAs) or mobile phones applications are not anymore restricted to multimedia or wireless communications, but have been extended to handle Global Navigation Satellite System (GNSS) functionalities. The new generation of portable ...

Energy-detection is appealing for IEEE 802.15.4a receivers as it allows to exploit the ranging capabilities and the multipath resistance of impulse-radio UWB at a reasonable complexity. IEEE 802.15.4a receivers operate with interference created by uncontro ...
We present a clock-offset tracking algorithm for impulse-radio ultra-wide band (IR-UWB) energy-detection receivers. There is a complexity versus performance trade-off for the design of IR-UWB energy-detection receivers: Extremely low-complexity energy-dete ...
