Which Criticism and Whose Humanism?apters 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 13–1. Deriving the carrier frequency and phase from the data bearing signal is the topic of this chapter.

Caroline Anglim,Bharat RanganathanThe purpose of timing recovery is to recover a clock at the symbol rate or a multiple of the symbol rate from the modulated waveform. This clock is required to convert the continuous-time received signal into a discrete-time sequence of data symbols.

Error ControlThe previous chapter concentrated on coding techniques for controlling the power spectrum of the transmitted signal. A side benefit is often the capability for limited error detection. A channel coder precedes the line coder as shown in figure 11–1, and is designed specifically for one of three purposes:
