An Introduction to Information Theory

An Introduction to Information Theory. Instructor: Prof. Adrish Banerjee, Department of Electrical Engineering, IIT Kanpur. Information Theory answers two fundamental questions: what is the maximum data rate at which we can transmit over a communication link, and what is the fundamental limit of data compression. In this course we will explore answers to these two questions. We will study some practical source compression algorithms. We will also study how to compute channel capacity of simple channels.

Lecture 08 - Variable to Block Length Coding

In this lecture we first describe how a source can be parsed into proper message set for variable to block length coding. Then we describe optimal variable to block length coding for a source parsed using proper message set (Tunstall coding).
