A key task of engineers is to design and analyse systems; however, they often have to do this without knowing a system's parameters. BSS is a very important area in signal processing as it enables engineers to derive the unknown inputs of a system from its known outputs. It also enables the separation of a set of signals from mixed set of signals. This is particularly important in telecommunications and biomedical engineering but is also key in speech, acoustic, audio and music processing and scientific data analysis. It is, therefore, a method that has wide applicability and is a very useful tool for many types of engineers and scientists in different fields. This Handbook is an ideal reference for university researchers, R&D engineers and graduates wishing to learn the core principles, methods, algorithms, and applications of Blind Source Separation. * The definitive reference: unlike other books, it contains the principles and all the major techniques and methods, cutting edge approaches and key application areas of Blind Source Separation * Edited by the pioneers in the field with contributions from 34 of the world's experts * Describes all the main existing numerical algorithms and gives practical advice on their design * Shows the applications of the methods to key application areas such as telecommunications, biomedical engineering, speech, acoustic, audio and music processing, while also giving a general method for developing applications
