Modulation Techniques
With that brief overview of the architectural elements of an RBB network, we now discuss some of the basic technology to make it all happen. We begin with the most basic problem of transmission: that of modulation technique.
Modulation techniques (also called line-coding techniques) are permutations of various properties of a constant waveform, such as amplitude, frequency, and phase, to encode uniqueness, which is, after all, information. Digital transmission through any medium (metal, fiber, or air) requires the use of modulation schemes to infuse digital information onto the medium. Modulation schemes differ as to speed of service they provide, quality of the medium they require, noise immunity, and complexity, which ...
