On multicasting nested message sets over combination networks

Suhas Diggavi, Vinod Malathidevi Prabhakaran, Shirin Saeedi Bidokhti

In this paper, we study delivery of two nested message sets over combination networks with an arbitrary number of receivers, where a subset of receivers (public receivers) demand only the lower priority message and a subset of receivers (private receivers) ...

Broadcasting and Multicasting Nested Message Sets

Shirin Saeedi Bidokhti

Finding theoretical limits on the performance of communication systems and designing schemes to achieve them is one of the fundamental questions in information theory. While the theory of point-to-point communication is well-investigated, most problems hav ...

Reducing recombination in ZnO photoanodes for dye sensitised solar cells through simple chemical synthesis

Michael Graetzel, Vincent Laporte, Lioz Etgar

A method has been developed to synthesise zinc oxide nanowire arrays that demonstrate superior device performance compared to conventional ZnO nanowires within dye sensitised solar cells (DSSCs). This simple yet effective methodology has produced nanowires ...

Looking Inside Modern Receivers

Pierre-André Farine, Cyril Botteron

The principle of wireless communications originates from the need to communicate between two points separated by a distance sufficiently large to prevent the use of wires. This article talks about modern receivers in which the basic building blocks of mode ...

Sampling of Sparse Channels with Common Support

Martin Vetterli, Ali Hormati, Yann Barbotin

The present paper proposes and studies an algorithm to estimate chan- nels with a sparse common support (SCS). It is a generalization of the classical sampling of signals with Finite Rate of Innovation (FRI) and thus called SCS-FRI. It is applicable to OFD ...

CAD tools for fast analysis of parasitic coupling and mismatch effects in switched-capacitor circuits

Maher Kayal, François Krummenacher, Sylvain Maréchal

This paper presents a switched-capacitor simulator, optimized for fast computations. Two CAD tools are implemented in order to perform Monte-Carlo simulations, to identify sensitive parasitic coupling prior to layout and to rapidly verify parasitic couplin ...
