==== What about non-Gaussian? ==== \\ **Description**\\ In many engineering problems, Gaussian noise is assumed. Sometimes for good reasons, sometimes for convenience. In information theory, another important property of Gaussian distributions, is that they maximize the entropy under a variance constraint. However, in many multi-user problems, this property is not sufficient to figure out the capacity achieving inputs. Indeed it could be helpful to use non-Gaussian input distributions. But non-Gaussian input distributions are hard to analyze over Gaussian noise channels. In [1], a technique using Hermite polynomials has been proposed for that purpose. The Goal of the project is to study this technique and its application to some problem. \\ **Perequisit**\\ Information theory, probability, analysis. The project can be approached from a more theoretic or applied persepctive. [1] E. Abbe, L. Zheng, "Coding Along Hermite Polynomials for Gaussian Noise Channels", ISIT 2009, Seoul.
