Preface

It is a great honor and pleasure for me to introduce this book "Applications of Digital Signal Processing" being published by InTech. The field of digital signal processing is at the heart of communications, biomedicine, defense applications, and so on. The field has experienced an explosive growth from its origins, with huge advances both in fundamental research and applications.

In this book the reader will find a collection of chapters authored/co-authored by a large number of experts around the world, covering the broad field of digital signal processing. I have no doubt that the book would be useful to graduate students, teachers, researchers, and engineers. Each chapter is self-contained and can be downloaded and read independently of the others.

This book intends to provide highlights of the current research in the digital signal processing area, showing the recent advances in this field. This work is mainly destined to researchers in the digital signal processing related areas but it is also accessible to anyone with a scientific background desiring to have an up-to-date overview of this domain. These nineteenth chapters present methodological advances and recent applications of digital signal processing in various domains as telecommunications, array processing, medicine, astronomy, image and speech processing.

Finally, I would like to thank all the authors for their scholarly contributions; without them this project could not be possible. I would like to thank also to the In-Tech staff for the confidence placed on me to edit this book, and especially to Ms. Danijela Duric, for her kind assistance throughout the editing process. On behalf of the authors and me, we hope readers enjoy this book and could benefit both novice and experts, providing a thorough understanding of several fields related to the digital signal processing and related areas.
