Chapter 3
Modulation Schemes
The first two chapters of this book have given you the fundamentals necessary to understand more complex topics associated with communications technologies. Modulation and multiplexing are the principles of moving information with progressively more efficient methods. We will use the knowledge gained in the previous chapters to help us understand specific information transfer methods. We will examine the radio-frequency spectrum, the modulation schemes that are used to maximize the limited resources of the spectrum, and new and emerging techniques of multiplexing that allow us to pack more information into a limited space on the spectrum. This examination will give us the information necessary to understand how ...
