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 03 - Introduction to Error Control Coding III |
In this lecture, we will first describe the classification of error control codes into block codes and convolutional codes. We will then describe the maximum likelihood decoding rule and illustrate the same using communication over binary symmetric channel. We will also describe what is meant by forward error correction (FEC), automatic repeat request (ARQ) and hybrid ARQ (HARQ).
