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 26 - Decoding of Low Density Parity Check Codes II: Belief Propagation Algorithm |
In this lecture we will describe the decoding over AWGN channel of low density parity check codes. We will derive the expressions used in message passing belief propagation algorithm. We will illustrate the decoding with an example.
