Summary; Bibliography; IndexBlind identification consists of estimating a multi-dimensional system only through the use of its output, and source separation, the blind estimation of the inverse of the system. Estimation is generally carried out using different statistics of the output. The authors of this book consider the blind identification and source separation problem in the complex-domain, where the available statistical properties are richer and include non-circularity of the sources - underlying components. They define identifiability conditions and present state-of-the-art algorithms that are based on algebraDigital signal and image processing series.Signal processingStatistical methodsSignal processingStatistical methods.108Moreau Eric958804Adali Tülay845678MiAaPQMiAaPQMiAaPQBOOK9910822663203321Blind identification and separation of complex-valued signals2897840UNINA
