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 24 - Low Density Parity Check Codes |
In this lecture we first define what is a low density parity check matrix and show how the parity check matrix can be represented using Tanner Graph. Next we talk about some simple random constructions as well constructions based on permutation matrix for low density parity check codes.
