An Introduction to Coding Theory
An Introduction to Coding Theory. Instructor: Dr. 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 linear block codes and convolutional codes, their encoding and decoding techniques as well as their applications in real world scenarios. Starting from simple repetition codes, we will discuss among other codes: Hamming codes, Reed Muller codes, low density parity check codes, and turbo codes. We will also study how from simple codes by concatenation we can build more powerful error correcting codes. (from nptel.ac.in)
| Lecture 20 - Decoding of Convolutional Codes II: 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.
