Chapter 3. Modulation and Coding
IN THIS CHAPTER
Modulation and channel coding are fundamental components of a digital communication system. Modulation is the process of mapping the digital information to analog form so it can be transmitted over the channel. Consequently every digital communication system has a modulator that performs this task. Closely related to modulation is the inverse process, called demodulation, done by the receiver to recover the transmitted digital information. The design of optimal demodulators is called detection theory. An OFDM system performs modulation and demodulation for each subcarrier separately, although usually in a serial fashion, to reduce complexity.
