Aside from presenting new directions and algorithms for robust image authentication in the presence of noise, as well as image correction, this book also:Provides an overview of the state of the art algorithms for image authentication in the presence of noise and modifications, as well as a comparison of these algorithms,Presents novel algorithms for robust image authentication, whereby the image is tried to be corrected and authenticated,Examines different views for the solution of problems connected to image authentication in the presence of noise,Shows examples, how the new techniques can be applied to image authentication, watermarking and biometry.This book is written on the one hand for students, who want to learn about image processing, authentication, watermarking and biometry, and on the other hand for engineers and researchers, who work on aspects of robustness against modifications of secure images.
Covers the Chinese DTTB standard which was announced recently and hasn’t been covered in detail Introduces the SFN network using the successful implementation of DTMB in Hong Kong as an example Introduces the latest announced systems including the ATSC M/H and DVB-NGH
The new edition contains:
• Expanded coverage of the basic concepts to aid understanding
• New sections on filter sysnthesis, control theory and contemporary topics of speech and image recognition
• Full solutions to all questions and exercises in the book
Assuming the reader already has some prior knowledge of signal theory, this textbook will be highly suitable for undergraduate and postgraduate students in electrical and electronic engineering taking introductory and advanced courses in DSP, as well as courses in communications and control systems engineering. It will also prove an invaluable introduction to DSP and its applications for the professional engineer.Expanded coverage of the basic concepts to aid understanding, along with a wide range of DSP applicationsNew textbook features included throughout, including learning objectives, summary sections, exercises and worked examples to increase accessibility of the textFull solutions to all questions and exercises included in the book
The scope of this book encompasses signal sources, radio propagation and modulation, cabling, high speed data systems, switching, LANs and WANs, multiplexing, and the whole range of telecomms equipment: telephone systems, mobile phones, pagers, modems, fax, private mobile radio...
Review of the previous edition
'There is something relevant to all practising telecommunications engineers and the book will be particularly valuable to those looking for a basic but sound appreciation of fields outside their particular speciality. In short an excellent book.' BT Engineering Journal
All sections have been thoroughly updated to cover the latest developments in technology and standards, including ITU regulations, WAP, GSM1800, HDSL2, wireless local loops and wireless broadband, optical fibre amplifiers and the latest submarine cable systems.
A practical engineer's reference that puts the key information at your fingertips
Covers essential data, techniques and working practice
This update includes the latest international regulations
in modern communications systems. Their basic principles are always derived with a focus on the resulting communications and implementation performance. As a result, this book serves as a valuable reference for two, typically disparate audiences in communication systems and hardware design.
Highlights of this edition:
-New material on error correction codes, multiple access, digital modulation, digital subscriber lines, cable modems, mobile wireless, wide area networks, and optical networks;
-Up-to-date industry standards and practices - including voice/video coding, digital subscriber lines, SONET/SDH, DWDM, ATM, broadband wireless access, network synchronization, and network management - are described and interpreted;
-Expanded problem sets (totaling over 300) at the end of each chapter for review and practice;
-All chapters have been updated with particular emphasis given to fiber optics, wireless and networks.
Practicing engineers in the field of communication systems, managers and technical personnel in the IT industry, and students of electrical and communications engineering will find this an authoritative state-of-the-art resource.
This book is intended to be a concise summary of the present state of the art of the theory and practice of OFDM technology. This book offers a unified presentation of OFDM theory and high speed and wireless applications. In particular, ADSL, wireless LAN, and digital broadcasting technologies are explained.
It is hoped that this book will prove valuable both to developers of such systems, and to researchers and graduate students involved in analysis of digital communications, and will remain a valuable summary of the technology, providing an understanding of new advances as well as the present core technology.
