Webbmultiple propagation paths. This energy extraction process is also known as time diversity. The first step in demodulating spread spectrum signals is synchronization, which is handled in two steps: acquisition and tracking. Acquisition is obtained by using the three synchronization pulses that precede the data packet. A DLL is Webbrelated to the spread-spectrum processing gain, which is essentially the ratio of the RF bandwidth to the information bandwidth. Spread spectrum uses wideband, noise-like …
