Opis

Unsupervised Signal Processing: Channel Equalization and Source Separation provides a unified, systematic, and synthetic presentation of the theory of unsupervised signal processing. Always maintaining the focus on a signal processing-oriented approach, this book describes how the subject has evolved and assumed a wider scope that covers several topics, from well-established blind equalization and source separation methods to novel approaches based on machine learning and bio-inspired algorithms. From the foundations of statistical and adaptive signal processing, the authors explore and elaborate on emerging tools, such as machine learning-based solutions and bio-inspired methods. With a fresh take on this exciting area of study, this book:

• Provides a solid background on the statistical characterization of signals and systems and on linear filtering theory
• Emphasizes the link between supervised and unsupervised processing from the perspective of linear prediction and constrained filtering theory
• Addresses key issues concerning equilibrium solutions and equivalence relationships in the context of unsupervised equalization criteria
• Provides a systematic presentation of source separation and independent component analysis
• Discusses some instigating connections between the filtering problem and computational intelligence approaches.

Building on more than a decade of the authors work at DSPCom laboratory, this book applies a fresh conceptual treatment and mathematical formalism to important existing topics. The result is perhaps the first unified presentation of unsupervised signal processing techniques one that addresses areas including digital filters, adaptive methods, and statistical signal processing. With its remarkable synthesis of the field, this book provides a new vision to stimulate progress and contribute to the advent of more useful, efficient, and friendly intelligent systems."

Unsupervised Signal Processing: Deconvolution, Identification, and Separation provides a unified and systematic presentation of topics such as blind equalization, source separation, and unsupervised as well as nonlinear adaptive filtering. Extending classical results in literature, this book addresses new issues on static and dynamic convergence of Bussgang algorithsm. It explores emergent trends like neuro-fuzzy systems and evolutionary algorithms. The text pays special attention to the equivalence relations between the different unsupervised criteria, including the relationships with Wiener theory. It also includes applications to wireless communications and MIMO systems.
