Information Theory, Coding and Cryptography

Foreword

The knowledge of information theory and coding has become a necessity not only for the electrical communication engineers, computer scientists, and information technologists but also for all others dealing with information, data, and signal flow. To know the principles of operations, to work for research and developments, to know more about applications, and to work with new futuristic topics such as nanotechnology, bioinformatics, etc., a thorough knowledge of information theory and coding is essential. Shannon’s theorem has given a beginning to this subject area which later on led to the development of several breakthrough concepts. Coding of information, data (audio, video, multimedia), and signals has become a necessity not only for error-free transmission/reception but also for reduction in storage space and for security of data/information. Cryptography, steganography, and watermarking are some of the examples of information security.

Prof. Arijit Saha, Prof. Nilotpal Manna, and Prof. Surajit Mandal are involved in teaching this subject for many years to the senior undergraduate students of B. P. Poddar Institute of Management and Technology and JIS College of Engineering both affiliated to West Bengal University of Technology, Kolkata. This book is the result of their sincere teaching using several books and journal papers. This book will address the needs of students studying this subject so that they get the study material in one source. The authors tried to cover the syllabi of all major universities and institutes of India, in general, and West Bengal University of Technology, in particular. In addition, they have included several advanced topics so that the book is suitable as a reference book for post-graduate students and practicing professionals. Some prominent aspects of the book are as follows:

• A brief but enough discussion on the mathematical and other prerequisites of the subject.
• Detail discussion on the theory and applications of all the topics, namely information theory, source codes, error control codes, linear block codes, cyclic codes, BCH codes, convolution codes.
• Discussions on advanced topics such as adaptive Huffman code, predictive code, LWZ code, MPEG, Dolby, interleaving techniques, CIRC coding, etc.
• A large number of solved examples to illustrate the concepts and at the end of each chapter, a large number of multiple choice questions with answers in each chapter, and a large number of problems in each chapter for practice.
• A good balance between theoretical and practical aspects of the subject. It provides a solid foundation of the subject for practicing professionals.
• Coverage of almost all the information of this subject area.

I am sure this book will serve the needs of the student community and will find an important place in Libraries.
