Today's wireless communications systems employ the latest digital modulation and multiple access techniques. Many standards have evolved to spur commercial applications.
This tutorial offers an explanation of the concepts behind orthogonal frequency division multiplexing (OFDM).
A collection calculators, such as:
Web apps are utilized in the tutorials to allow you to experiment with the concepts
This tutorial applet demonstrates how the process of encoding and decoding CDMA user signals works. The user interface is in German but it is fairly easy to understand that the applet is combining data from four users.
This website features a comprehensive glossary of RF and Microwave terms along with many "rules of thumb" practical articles. It is now affiliated with the IEEE Microwave Theory and Techniques society.
The only easy-to-understand guide to the wireless revolution...
This site is full of well-written tutorials on wireless communications and DSP topics.
A Java applet that let's you experiment with the Fourier series for different wave shapes. You can also listen to the waveforms.
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.
This film from the AT&T archives provides and explanation of the original analog cellular phone system. It provides and interesting description of the limited mobile phone system that existed before cellular phones were developed, as well as describing the original AMPS service and the "cellular" concept, which still applies today.
Master every key digital communications technology, concept, and technique.
Digital Communications, Second Edition is a thoroughly revised and updated edition of the field's classic, best-selling introduction. With remarkable clarity, Dr. Bernard Sklar introduces every digital communication technology at the heart of today's wireless and Internet revolutions, providing a unified structure and context for understanding them -- all without sacrificing mathematical precision.
