Robust Non-Coherent Timing Acquisition in IEEE 802.15.4a IR-UWB Networks

Jean-Yves Le Boudec, Ruben Merz, Manuel Flury

Non-coherent energy-detection receivers are an attractive choice for IEEE 802.15.4a networks. They can exploit the ranging capabilities and the multipath resistance of impulse-radio ultra-wide band (IR-UWB) at a low complexity. However, IEEE 802.15.4a rece ...

Performance Evaluation of Impulse Radio UWB Networks using Common or Private Acquisition Preambles

Jean-Yves Le Boudec, Ruben Merz

For impulse-radio ultra-wide band (IR-UWB) networks without global synchronization, the first step for correct packet reception is packet detection and timing acquisition: Before recovering the payload of the packet, the destination must detect that the pa ...

Robust IEEE 802.15.4a Energy Detection Receiver Using Statistical Interference Modeling

Jean-Yves Le Boudec, Ruben Merz, Manuel Flury

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 ...

Clock-Offset Tracking Software Algorithms For IR-UWB Energy-Detection Receivers

Jean-Yves Le Boudec, Ruben Merz, Manuel Flury

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 ...

Interference management in impulse-radio ultra-wide band networks

Ruben Merz

We consider networks of impulse-radio ultra-wide band (IR-UWB) devices. We are interested in the architecture, design, and performance evaluation of these networks in a low data-rate, self-organized, and multi-hop setting. IR-UWB is a potential physical la ...

Method for retrieving data from Ultra Wideband radio transmission signals

Jean-Yves Le Boudec, Ruben Merz, Manuel Flury

The present invention concerns a receiver and a method for retrieving data from Ultra wideband radio transmission signals received by a receiver and transmitted in packets containing at least a preamble known to the receiver and a payload containing data u ...

An Energy Detection Receiver Robust to Multi-User Interference for IEEE 802.15.4a Networks

Jean-Yves Le Boudec, Ruben Merz, Manuel Flury

Energy-detection receivers are appealing to IEEE 802.15.4a low data-rate networks because of their low complexity. With a reasonable energy consumption, these receivers can exploit the ranging capabilities and multipath resistance of impulse-radio UWB (IR- ...

Concurrent and Parallel Transmissions are Optimal for Low Data-Rate IR- UWB Networks

Jean-Yves Le Boudec, Ruben Merz

The Internet of Things, emerging pervasive and sensor networks are low data-rate wireless networks with, a priori, no specific topology and no fixed infrastructure. Their primary requirements are twofold: First, low power consumption and, due to environmen ...

Performance Evaluation of an IEEE 802.15.4a Physical Layer with Energy Detection and Multi-User Interference

Jean-Yves Le Boudec, Ruben Merz, Manuel Flury

We evaluate the performance of an IEEE 802.15.4a ultra-wide band (UWB) physical layer, with an energy-detection receiver, in the presence of multi-user interference (MUI). A complete packet based system is considered. We take into account packet detection ...

Managing Impulsive Interference in Impulse Radio UWB Networks

Jean-Yves Le Boudec, Ruben Merz, Manuel Flury

Wireless sensor networks are ideally built on low-cost, low-complexity nodes that have a low power consumption to guarantee a long network lifetime. These are all properties that can potentially be achieved with impulse radio ultra-wide band (IR-UWB). In a ...
