Effect of Digitally Modulated Signals on Multipactor Breakdown

Juan Ramon Mosig, Michael Mattes, Apostolos Sounas

This paper studies the effect of digitally modulated signals on the evolution of the multipaction phenomenon. Multipactor is numerically analyzed in a parallel plates waveguide for a variety of common digital modulation techniques. Breakdown power threshol ...

A novel low complexity data demodulation algorithm for pulse position modulation

Pierre-André Farine, Cyril Botteron

In this paper, a low complexity data demodulation algorithm is proposed that requires time of arrival information of the received signal exclusively. As an application example, the algorithm is applied to an ultra-wideband impulse radio communication syste ...

A Distributed Interleaving Scheme for Efficient Access to WideIO DRAM Memory

Giovanni De Micheli, Luca Benini, Ciprian Seiculescu

Achieving the main memory (DRAM) required bandwidth at ac- ceptable power levels for current and future applications is a ma- jor challenge for System-on-Chip designers for mobile platforms. Three dimensional (3D) integration and 3D stacked DRAM mem- ories ...

Fast and Robust Parametric Estimation of Jointly Sparse Channels

Martin Vetterli, Yann Barbotin

We consider the joint estimation of multipath channels obtained with a set of receiving antennas and uniformly probed in the frequency domain. This scenario fits most of the modern outdoor communication protocols for mobile access (ETSI Std. 125 913) or di ...

We address the problem of prioritized video streaming over lossy overlay networks. We propose to exploit network path diversity via a novel Randomized Network Coding (RNC) approach that provides unequal error protection (UEP) to the packets conveying the v ...

Compressive Sampling of Multiple Sparse Signals Having Common Support Using Finite Rate of Innovation Principles

Martin Vetterli, Ali Hormati

In sensor networks and communication systems, one is often confronted with sampling multiple sparse signals having a common support set. Multipath channels in a multiple-input multiple-output (MIMO) wireless communication setting is an interesting example ...

Institute of Electrical and Electronics Engineers2011

In this paper, we study a Gaussian relay-interference network, in which relay (helper) nodes are to facilitate competing information flows between different source-destination pairs. We focus on two-stage relay-interference networks where there are weak cr ...

Coexistence of Multiple HomePlug AV Logical Networks: A Measurement Based Study

Jean-Yves Le Boudec, Alaeddine El Fawal, Zhang Liu

HomePlug AV (HPAV) was designed to provide high speed in-home communication with 200Mbps PHY rate, with the goal to overcome various noises over power wires and to jump from one phase to a neighboring one. A HomePlug AV Logical Networks (AVLN) is defined b ...

ACCOP: Adaptive Cost-Constrained and Delay- Optimized Data Allocation over Parallel Opportunistic Networks

Hamza Harkous

As wireless and mobile technologies are becoming increasingly pervasive, an uninterrupted connectivity in mobile devices is becoming a necessity rather than a luxury. When dealing with challenged networking environments, this necessity becomes harder to ac ...
