Blind source separation refers to the inferring of the values of variables (known as sources) from observations that are linear combinations of them. The observations and sources are usually vectors. Both the sources and the matrix of linear coefficients may be unknown. Here we describe an approach ...

This article proposes a robust way to estimate the scale parameter of a generalised centered Gaussian mixture. The principle relies on the associationof samples of this mixture to generate samples of a new variable that shows relevant distribution properties to estimate the unknown parameter.In fact ...
