Blind source separation, often called independent component analysis, is a main field of research in signal processing since the eighties. It consists in retrieving the components, up to certain indeterminacies, of a mixture involving statistically independent signals. Solid theoretical results are known; besides, they have given rise to performance algorithms. There are numerous applications of blind source separation. In this ...
