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 03 - Introduction to Error Control Coding III |
In this lecture, we will first describe the classification of error control codes into block codes and convolutional codes. We will then describe the maximum likelihood decoding rule and illustrate the same using communication over binary symmetric channel. We will also describe what is meant by forward error correction (FEC), automatic repeat request (ARQ) and hybrid ARQ (HARQ).
