Error control Coding: An Introduction to Linear Block Code
Error control Coding: An Introduction to Linear Block Code. 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 linear block 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 capacity approaching low density parity check codes. We will also discuss bounds on number of codewords given codeword length and minimum distance of code. (from nptel.ac.in)
Lecture 15 - 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.
