Method of controlling synchronization signal power in a spread spectrum communication system.

摘要

To initiate communication, a first station generates a synchronization signal and sends it to a second station. When the second station detects the synchronization signal, it acquires synchronization and sends a synchronization-acquisition message back to the first station. The first station now reduces the power of the synchronization signal, but continues to send the synchronization signal, and also begins sending a modulated data signal. The second station uses the synchronization signal to maintain synchronization for demodulating the data signal.
