Information Theory and Coding

Course aim

The first part of this course is about information theory. The course aims at answering two fundamental questions in data communications: What is the ultimate data compression? What is the ultimate transmission rate of a communication channel? To answer these questions, the basic tools and concepts in information theory are introduced. Practical coding schemes for data compression and transmission over noisy channels are introduced in the second part of this course.
