OFDM

This app note gives an overview of the physical layer (radio) aspects of Long Term Evolution (LTE) plans for cellular systems. It provides a good summary of the important concepts.

This tutorial offers an explanation of the concepts behind orthogonal frequency division multiplexing (OFDM).

A collection calculators, such as:

• Wave propagation calculation tool (for free-space and 2 wave model)
• Fresnel zone calculation tool
• Okumura-Hata curve calculation tool
• Creating a channel plan in order to avoid third-order intermodulation interference and the near-far problem tool
• Height pattern calculation tool
• Mutual conversion of decibel value and true value

Web apps are utilized in the tutorials to allow you to experiment with the concepts

In this 5th Edition, the author continues to evaluate various novel techniques and design methods for the modulation and transmission of digital data, allowing the readers to gain a firm understanding of the processes needed to effectively design wireless data link communication systems. Since the author regularly runs industry seminars based on this book, he is continuously updating the book material. This edition includes thorough updates of all chapters including all concepts and revised and new figures.

The stated purpose of this tutorial from the University of Edinburgh is to give a simple introduction to Orthogonal Frequency Division Multiplexing. This is a somewhat technical OFDM demo.
