Sommario/riassunto

Blind 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 algebra

Sommario/riassunto

This volume brings together contributions from a variety of disciplines to address the writer's legacy and literary achievements. Essays on previously unexplored topics and reflective pieces on McGahern as a writer illuminate his body of work in new and challenging ways, expanding the boundaries of the McGahern debate.
