Reduced-Dimension Linear Transform Coding of Correlated Signals in Networks

Michael Christoph Gastpar, Naveen Goela

A model called the linear transform network (LTN) is proposed to analyze the compression and estimation of correlated signals transmitted over directed acyclic graphs (DAGs). An LTN is a DAG network with multiple source and receiver nodes. Source nodes tra ...

Looking Inside Modern Receivers

Frédéric Chastellain, 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, Yann Barbotin, Ali Hormati

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 ...
