补充一下这本书的前言和目录
This book is an evolution from my book A First Course in Information Theory published in 2002 when network coding was still at its infancy. The last few
years have witnessed the rapid development of network coding into a research eld of its own in information science. With its root in information theory,
network coding not only has brought about a paradigm shift in network communications at large, but also has had signicant in
uence on such specic research elds as coding theory, networking, switching, wireless communications,distributed data storage, cryptography, and optimization theory. While new applications of network coding keep emerging, the fundamental results that lay the foundation of the subject are more or less mature. One of the main goals of this book therefore is to present these results in a unifying andcoherent manner.
While the previous book focused only on information theory for discrete random variables, the current book contains two new chapters on information
theory for continuous random variables, namely the chapter on dierential entropy and the chapter on continuous-valued channels. With these topics
included, the book becomes more comprehensive and is more suitable to beused as a textbook for a course in an electrical engineering department.
Out of the twenty-one chapters in this book, the rst sixteen chapters belong to Part I, Components of Information Theory, and the last ve chapters
belong to Part II, Fundamentals of Network Coding. Part I covers the basic topics in information theory and prepare the reader for the discussions in
Part II. |
