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 30 - Distance Properties of Turbo Codes |
In this lecture, with a help of an example we first explain spectral thinning of parallel concatenated codes. Next using the concept of uniform interleaver, we compute the average WEF, IRWEF, CWEF, and bit CWEF of turbo codes. We illustrate the procedure with a simple example of parallel concatenated block codes.
