Limits of Communicationt communication, and stimulated considerable intellectual activity, both practical and theoretical. This theory, among other things, gives us some fundamental boundaries within which communication can take place. Often we can gain considerable insight by comparing the performance of a digital communication system design with these limits.

Noiseceivers for a channel model that includes additive white Gaussian noise. As discussed in Chapter 5, Gaussian noise models thermal noise and high-density shot noise, as found in cable, radio, and fiber optic channels.

Carrier Recoveryapters 6 and 8, . of a passband signal requires exactly the same carrier frequency and phase to perform the demodulation. But the receiver usually has an independent timing reference, as illustrated in Figure 15-1. Deriving the carrier frequency and phase from the data bearing signal is the topic of this chapter.

Introductionuter communication, the information to be transported is inherently digital, so digital transmission is the only practical alternative. But computer communication is still a small fraction of all digital communications. A much larger fraction is devoted to transmitting inherently analog signals, par
