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 09 - Decoding of Convolutional Codes: BCJR Algorithm |
In this lecture we will describe MAP decoding (BCJR algorithm) of a convolutional code. We will then illustrate the decoding algorithm with the help of a rate R=1/2 convolutional code with bits transmitted over additive white Gaussian noise (AWGN) channel.
