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 22 - Problem Solving Session V|
In this lecture we will solve problems related to feedforward inverse of convolutional encoders. We will describe the condition for existence of a feedforward inverse of a convolutional encoder. Further, we will show that catastrophic encoders do not have a feedforward inverse. Finally, we will prove a property related to an important distance measure (column distance function) for convolutional codes.
