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 ...

A low-power 2.4 GHz CMOS receiver using BAW resonators

Jérémie Chabloz

It has already been a few years since the first appearance of micro-electromechanical systems (MEMS) in academic research. Since then, a broad number of devices have been designed under this generic term. Bulk-acoustic wave (BAW) resonators are among the f ...

A Low-Power, Low Data-Rate, Ultra-Wideband Receiver Architecture for Indoor Wireless Systems

Pierre-André Farine, Cyril Botteron, Christian Robert, Frédéric Chastellain, Uroschanit Yodprasit, Alexander Heubi, Paul Saad

Abstract—In this paper, a novel architecture for a low data-rate, low power consumption Impulse Radio (IR) Ultra- Wideband (UWB) receiver is presented in which the received UWB signal is downconverted to a given intermediate frequency (IF) rather than at b ...

Diversity embedding for broadband communication

Sanket Dusad

Given uncertainty in environment, a conservative approach is to design for the worst case, leading to a game-theoretic situation where the environment is controlled by an adversary. However, in many cases, the uncertainty arises from randomness, not an adv ...

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 ...

Compensation of Phase Noise in OFDM Wireless Systems

Ali H. Sayed

Phase noise causes significant degradation in the performance of orthogonal frequency division multiplexing (OFDM)-based wireless communication systems. The presence of phase noise can reduce the effective signal-to-noise ratio (SNR) at the receiver, and c ...

An 11-Mb/s 2.1-mW Synchronous Superregenerative Receiver at 2.4 GHz

Catherine Dehollain, Michel Declercq

This paper presents a low-voltage low-power high-speed superregenerative receiver operating in the 2.4-GHz industrial-scientific-medical band. The receiver uses an architecture in which, thanks to the presence of a phase-locked loop, the quench oscillator ...

A phase noise compensation scheme for OFDM wireless systems

Ali H. Sayed

Phase noise causes significant degradation in the performance of Orthogonal Frequency Division Multiplexing (OFDM) based wireless communication systems. In the proposed compensation scheme, the communication between the transmitter and receiver blocks cons ...

Convergence analysis for sequential Monte Carlo receivers in communications applications

Volkan Cevher

Recently, sequential Monte Carlo methods have been used in the telecommunications field, finding application in receiver design. Several properties of these receivers make their designs very attractive. These receivers do not require channel state informat ...
