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.作者: 舊病復(fù)發(fā) 時間: 2025-3-23 08:50
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:作者: 無辜 時間: 2025-3-23 12:07
