Acoustic MIMO Signal Processing

Telecommunication systems and human-machine interfaces have begun using multiple microphones and loudspeakers to make conversation and interaction more lifelike, and hence more efficient. This development raises a variety of acoustic signal processing problems under multiple-input multiple-output (MIMO) scenarios, encompassing distant speech acquisition, sound source localization and tracking, echo and noise control, source separation and speech dereverberation, and many others. Acoustic MIMO Signal Processing presents the theoretical and the practical in separate sections. The authors open by introducing an acoustic MIMO paradigm, establishing the fundamental of the field, and linking acoustic MIMO signal processing with the concepts of classical signal processing and communication theories in terms of system identification, equalization, and adaptive algorithms. The second part of the book presents a novel and penetrating analysis of aforementioned acoustic applications that is carried out in the paradigm to reinforce the fundamental concepts of acoustic MIMO signal processing.

Investigates a variety of acoustic signal processing problems in a unified platform Presents different and new audio signal processing technologies for next-generation multimedia communication systems Covers new technologies such as spherical microphone arrays, multichannel acoustic echo cancellation, robust time delay estimation in reverberant environments for source localization and scene analysis, and virtual spatial sound

Telecommunication systems and human-machine interfaces start employing multiple microphones and loudspeakers in order to make conversations and interactions more lifelike, hence more efficient. This development gives rise to a variety of acoustic signal processing problems under multiple-input multiple-output (MIMO) scenarios, encompassing distant speech acquisition, sound source localization and tracking, echo and noise control, source separation and speech dereverberation, and many others. The last decade has witnessed a growing interest in exploring these problems, but there has been little effort to develop a theory to have all these problems investigated in a unified framework. This unique book attempts to fill the gap.

Acoustic MIMO Signal Processing is divided into two major parts - the theoretical and the practical. The authors begin by introducing an acoustic MIMO paradigm, establishing the fundamental of the field, and linking acoustic MIMO signal processing with the concepts of classical signal processing and communication theories in terms of system identification, equalization, and adaptive algorithms. In the second part of the book, a novel and penetrating analysis of aforementioned acoustic applications is carried out in the paradigm to reinforce the fundamental concepts of acoustic MIMO signal processing.

Acoustic MIMO Signal Processing is a timely and important professional reference for researchers and practicing engineers from universities and a wide range of industries. It is also an excellent text for graduate students who are interested in this exciting field.
