Introduction to Information Theory and Coding

Information Theory and Coding may be the fastest growing technologies in the field of Communication and network security. One of the ramifications of that growth is a dramatic increase in the number of professions-where an understanding of these technologies is essential for success-and a proportionate increase in the number and types of students taking course to learn about them.

Features of the Book 

Several features of this text are designed to make it particularly easy for students to understand information theory and coding. 

Course Objectives 

Course objectives are clearly defined at initial for all the chapters. 

Structure

This textbook is designed for students with little or no background in telecommunications or data communications. For this reason, we use a bottom-up approach. With this approach, students learn first about information system (bottom up approach) followed by generating the code words and code vectors using linear block codes and cyclic codes respectively.

 Visual Approach

 The book presents highly technical subject matter without complex formulas by using a balance of text and figures. More than 200 figures accompanying provide a visual and intuitive opportunity for understanding the material. Figures are particularly important and explaining coding concepts, which are based on connections and transmissions. Both of these ideas are easy to grasp visually. Highlighted Points We emphasize important concepts in highlighted boxes for quick references and immediate attention. Recommended Reading Each chapter includes a list of books and sites that can be used for further reading.

Recommended Reading 

Each chapter includes a list of books and sites that can be used for further reading. 

Key Terms 

Each chapter includes a list of key terms for the student. 

Practice Set 

Each chapter includes a practice set designed to reinforce and apply Salient concepts. It consists of two parts: descriptive questions and model exam question papers (end of all the chapters). Descriptive questions are intended to test the students first-level understanding of the material presented in the chapter. Multiple choice questions are designed to create motivation for the students to appear in the competitive examinations. Examination questions require deeper understanding of the material. 

Index 

The book contains an extensive list of acronyms. 

Organization 

The following lists the course material in the organization of the book: 

1. Chapter 1 discusses the brief Introduction of Information Theory. 

2. Chapter 2 deals with the generation of code words Source coding. 

3. Chapter 3 describes the various Communication Channels in the field of Communication. 

4. Chapter 4 discusses Error Control Codes for Linear Block Codes. 

5. Chapter 5 discuses Binary Cyclic Codes. 

6. Chapter 6 discusses Important Cyclic codes 

7. Chapter 7 deals with the convolution codes. 

Instructional Materials 

Instructional materials for both the student and the teacher are provided. The solutions to exercises contain both the explanation and answer including full colored figures or tables when needed. The PowerPoint presentations are more comprehensive and include text and figures. 

Contents 

The book is divided into seven parts. The first part is an introduction to Information theory; the second part is Source Coding; the third part is Informational Channels;  fourth chapter is Error Control Coding; Binary Cyclic codes are discussed in Chapter 5; Chapter 6 covers some important Cyclic codes and Chapter 7 covers the Convolution codes. The following summarizes the contents of each part.

How to Use the Book 

This book is written for both an academic and a professional audience. The book can be used as a self-study guide for interested professionals. As a textbook, it can be used for a one-semester course. The following are some guidelines.  Parts one to three are strongly recommended.  Parts four to seven can be covered to detect and correct the errors that lead to improve the efficiency of communication system. The book is intended for undergraduate and postgraduate students of Electronics and Communication Engineering, Computer Science and Engineering, Information Technology and Telecommunication Engineering. The course material in this book is already taught to students for many years by the author; and the book is written with better understanding of the needs of the students and the practicing engineers in the subject.
