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 17 - Convolutional Codes: Classification, Realization |
In this lecture we will first describe the classification of convolutional encoders as feedforward and feedback encoders, systematic and nonsystematic encoders. We will then introduce the notation of equivalent encoder and describe catastrophic encoder. We will show how the convolutional code can be realized using controller canonical form realization and observer canonical form realization. Finally, we conclude with a brief description of minimal encoder.
