Wyner-Ziv Coding Based on Multidimensional Nested Lattices
Cong Ling, Su Gao, Jean-Claude Belfiore
Distributed source coding (DSC) addresses the compression of correlated sources without communication links among them. This paper is concerned with the Wyner-Ziv problem: coding o…
An Error Probability Approach to MIMO Wiretap Channels
Jean-Claude Belfiore, Frédérique Oggier
We consider MIMO (Multiple Input Multiple Output) wiretap channels, where a legitimate transmitter Alice is communicating with a legitimate receiver Bob in the presence of an eaves…
The Compute-and-Forward Protocol: Implementation and Practical Aspects
Ali Osmane, Jean-Claude Belfiore
In a recent work, Nazer and Gastpar proposed the Compute-and-Forward strategy as a physical-layer network coding scheme. They described a code structure based on nested lattices wh…
Lattice Codes for the Wiretap Gaussian Channel: Construction and Analysis
Frédérique Oggier, Patrick Solé, Jean-Claude Belfiore
We consider the Gaussian wiretap channel, where two legitimate players Alice and Bob communicate over an additive white Gaussian noise (AWGN) channel, while Eve is eavesdropping, a…
Constructive spherical codes near the Shannon bound
Patrick Solé, Jean-Claude Belfiore
Shannon gave a lower bound in 1959 on the binary rate of spherical codes of given minimum Euclidean distance . Using nonconstructive codes over a finite alphabet, we give a lowe…
