Error Control Coding: An Introduction to Convolutional Codes

Error Control Coding: An Introduction to Convolutional Codes. Instructor: Prof. Adrish Banerjee, Department of Electrical Engineering, IIT Kanpur. Error control coding is an indispensable part of any digital communication system. In this introductory course, we will discuss theory of convolutional codes, their encoding and decoding techniques as well as their applications in real world scenarios. We will also study how from simple codes by concatenation we can build more powerful error correcting codes. In particular, we will study in details, one such capacity approaching codes called turbo codes. (from nptel.ac.in)

Lecture 01 - Introduction to Error Control Coding I

In this lecture, we will give a brief introduction of error control coding. With the help of simple repetition code, we will illustrate how error correcting codes can be used for error detection and error correction. We will also describe two simple channel models, namely binary symmetric channel and binary erasure channel.
