1. A method of synchronizing a first station to a second station in a communication system, comprising the steps of:

  • (a) generating a synchronization signal at said first station;

    (b) sending said synchronization signal from said first station to said second station at a first power level;

    (c) detecting said synchronization signal at said second station and acquiring synchronization therewith;

    (d) sending a synchronization-acquisition message from said second station to said first station;

    (e) reducing said synchronization signal to a second power level lower than said first power level;

    (f) generating, at said first station, a modulated data signal, said modulated data signal being modulated in synchronization with said synchronization signal;

    (g) sending both said synchronization signal and said modulated data signal from said first station to said second station, said synchronization signal being at said second power level and said modulated data signal being at a power level higher than said second power level; and

    (h) demodulating said modulated data signal at said second station, in synchronization with said synchronization signal.
