An Introduction to Coding Theory

About the course
Error control coding is an indispensible 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.

Intended Audience
3rd/4th year UG students, PG students & faculty in electronics and communications engineering 

Prerequisites
An exposure to linear algebra and probability theory as well as a course in digital communications

Industries that will recognize this course
Telecommunication Companies
