Users of signal processing systems are never satis?ed with the system they currently use. They are constantly asking for higher quality, faster perf- mance, more comfort and lower prices. Researchers and developers should be appreciative for this attitude. It justi?es their constant e?ort for improved systems. Better knowledge about biological and physical interrelations c- ing along with more powerful technologies are their engines on the endless road to perfect systems. This book is an impressive image of this process. After “Acoustic Echo 1 and Noise Control” published in 2004 many new results lead to “Topics in 2 Acoustic Echo and Noise Control” edited in 2006 .

The functionality of new systems is less and less limited by the processing power available under economic constraints. The editors have to thank all the authors for their contributions. They cooperated readily in our e?ort to unify the layout of the chapters, the ter- nology, and the symbols used. It was a pleasure to work with all of them. Furthermore, it is the editors concern to thank Christoph Baumann and the Springer Publishing Company for the encouragement and help in publi- ing this book.

Dieses Lehrbuch behandelt statistische Signalmodelle aus der Sicht der Systemtheorie. Es entstand aus Vorlesungen des Autors an der TH Darmstadt für Studenten der Nachrichten- und Regelungstechnik nach dem Vorexamen. Im Gegensatz zur klassischen Theorie werden in diesem Buch Signale durch Zufallsprozesse modelliert. Nach einem kurzen Abriß der wichtigsten Gesetze der Wahrscheinlichkeitsrechnung werden Zufallsvariable und Zufallsprozesse behandelt. Hieran schließt sich die Betrachtung der Zusammenhänge zwischen den Eigenschaften des Eingangs- und des Ausgangsprozesses eines Systems an. Breiten Raum nehmen dabei Korrelationsfunktionen und Leistungsdichtespektren ein. Im zweiten Teil des Buches werden Anwendungen statistischer Sig- nalmodelle dargestellt. Im Vordergrund steht dabei die Optimierung linearer Systeme. Im einzelnen werden diskutiert: Signalangepaßtes Filter, Prädiktor, Optimalfilter nach Wiener und Kolmogoroff, Kalman-Filter und adaptive Filter. Die einzelnen Abschnitte des Buches beginnen in der Regel mit einer kurzen Herleitung oder einer Definition. Anschließend werden die neu eingeführten Größen diskutiert und Verbindungen zu bereits bekannten Zusammenhängen hergestellt. Jeder Abschnitt schließt mit durchgerechneten Beispielen. Die Darstellung des Stoffes bewegt sich auf dem Mittelweg zwischen "rein anschaulich" und "streng formal". Das Buch gibt daher einem Praktiker einen ausreichenden Hintergrund für den experimentellen Umgang mit Signalen. Gleichzeitig bereitet es Theoretiker auf das Studium weiterführender Darstellungen vor.

A Perspective on Single channel Frequency domain Speech Enhancement

This book focuses on a class of single-channel noise reduction methods that are performed in the frequency domain via the short-time Fourier transform (STFT). The simplicity and relative effectiveness of this class of approaches make them the dominant choice in practical systems. Even though many popular algorithms have been proposed through more than four decades of continuous research, there are a number of critical areas where our understanding and capabilities still remain quite rudimentary, especially with respect to the relationship between noise reduction and speech distortion. All existing frequency-domain algorithms, no matter how they are developed, have one feature in common: the solution is eventually expressed as a gain function applied to the STFT of the noisy signal only in the current frame. As a result, the narrowband signal-to-noise ratio (SNR) cannot be improved, and any gains achieved in noise reduction on the fullband basis come with a price to pay, which is speech distortion. In this book, we present a new perspective on the problem by exploiting the difference between speech and typical noise in circularity and interframe self-correlation, which were ignored in the past. By gathering the STFT of the microphone signal of the current frame, its complex conjugate, and the STFTs in the previous frames, we construct several new, multiple-observation signal models similar to a microphone array system: there are multiple noisy speech observations, and their speech components are correlated but not completely coherent while their noise components are presumably uncorrelated. Therefore, the multichannel Wiener filter and the minimum variance distortionless response (MVDR) filter that were usually associated with microphone arrays will be developed for single-channel noise reduction in this book. This might instigate a paradigm shift geared toward speech distortionless noise reduction techniques.

Speech Dereverberation gathers together an overview, a mathematical formulation of the problem and the state-of-the-art solutions for dereverberation. Speech Dereverberation presents current approaches to the problem of reverberation. It provides a review of topics in room acoustics and also describes performance measures for dereverberation. The algorithms are then explained with mathematical analysis and examples that enable the reader to see the strengths and weaknesses of the various techniques, as well as giving an understanding of the questions still to be addressed. Techniques rooted in speech enhancement are included, in addition to a treatment of multichannel blind acoustic system identification and inversion. The TRINICON framework is shown in the context of dereverberation to be a generalization of the signal processing for a range of analysis and enhancement techniques. Speech Dereverberation is suitable for students at masters and doctoral level, as well as established researchers.

Nonlinear signal and image processing methods are fast emerging as an alternative to established linear methods for meeting the challenges of increasingly sophisticated applications. Advances in computing performance and nonlinear theory are making nonlinear techniques not only viable, but practical. This book details recent advances in nonlinear theory and methods and explores an array of modern signal and image processing applications. The first several chapters focus on nonlinear signal processing theory, targeting three critical areas: filter analysis, nonlinear filter class design, and signal analysis. The remaining chapters explore nonlinear approaches across the broad spectrum of applications with signal processing components, from data traffic modeling and image enhancement to cutting edge applications in genomics. All of the chapters were contributed by well-known theorists and application-driven researchers who explore current and emerging nonlinear methods from their theoretical background and practical algorithms through the potential of these methods for solving important open questions. Nonlinear Signal and Image Processing: Theory, Methods, and Applications thus provides a singular opportunity to build a strong, fundamental understanding of nonlinear theory and methods and a foundation upon which to approach many of today's most interesting and challenging signal processing problems.

Top researchers in the field contributed chapters addressing their specific topic of study. The topics are limited to acoustics, speech, wireless, and networking applications where research is still very active and open. The book is roughly organized into two parts. In the first part, several applications in acoustics and speech are developed. The second part focuses on wireless and networking applications. Some chapters are tutorial in nature ,while others present new research ideas, and all have in common, the use of adaptive algorithms to solve real-world problems.

This book focuses on the application of canonical correlation analysis (CCA) to speech enhancement using the filtering approach. The authors explain how to derive different classes of time-domain and time-frequency-domain noise reduction filters, which are optimal from the CCA perspective for both single-channel and multichannel speech enhancement. Enhancement of noisy speech has been a challenging problem for many researchers over the past few decades and remains an active research area. Typically, speech enhancement algorithms operate in the short-time Fourier transform (STFT) domain, where the clean speech spectral coefficients are estimated using a multiplicative gain function. A filtering approach, which can be performed in the time domain or in the subband domain, obtains an estimate of the clean speech sample at every time instant or time-frequency bin by applying a filtering vector to the noisy speech vector. Compared to the multiplicative gain approach, the filtering approach more naturally takes into account the correlation of the speech signal in adjacent time frames. In this study, the authors pursue the filtering approach and show how to apply CCA to the speech enhancement problem. They also address the problem of adaptive beamforming from the CCA perspective, and show that the well-known Wiener and minimum variance distortionless response (MVDR) beamformers are particular cases of a general class of CCA-based adaptive beamformers.

Oliver Sacks ist berühmt für seine brillanten Geschichten, die uns tief in die Welt des menschlichen Geistes und Gehirns führen und unser Verständnis des menschlichen Wesens erweitert haben und dies mit seiner einzigartigen Mischung aus empathischer Erzählkunst, wissenschaftlicher Gelehrsamkeit und dem Blick für das Kuriose. In seinem neuesten Buch erzählt Sacks von Menschen, die nach einer Hirnverletzung ihre Musikalität verlieren, und von anderen, die durch eine solche Verletzung erst Musikalität entwickeln, ja von Musik geradezu besessen sind. Sacks erweist sich wieder als Meister der Menschenbeschreibung und entdeckt an scheinbaren Defekten die besonderen Qualitäten der Menschen wie beim einarmigen Pianisten Paul Wittgenstein, für den die großen Komponisten Benjamin Britten, Paul Hindemith, Richard Strauss und Maurice Ravel eigens Stücke für die linke Hand schrieben. Musik, so zeigt Sacks, hat die einzigartige Kraft, das Gehirn in ganz bemerkenswerter und komplexer Weise zu verändern, und wir Menschen sind eine musikalische Spezies nicht nur eine sprachliche. Musik zieht uns unwiderstehlich in ihren Bann.
