THE GATEWAY to the exciting field!
on July 21, 2001
This book is a research-level books that guides you to the world of information theory. Many arguements in the book are closely related to those in the latest information theory papers. For instance, the line of thought of the proof of channel capacity theorem (achievability->error analysis->converse) are still used in many network information theory papers. Hence, not only can readers refer to other papers when learning the subject(esp network information theory), but also get a solid foundation if he wants to continue with information theory. Another point is the intuition employed throughout the book. Dr.Cover visualizes many abstract notions (e.g. typical set)in information theory with clear diagrams. The subject suddenly becomes more approachable, and more importantly, these techniques are very important in subsequent study of the subject. Finally, the broad coverage of the book (of coz, it has depth) provides reader with a sip of the creativity and eclectic nature of information theory. In sum, after reading the book, readers will have some idea of this exciting field! But of coz, this is only the beginning!
