Patent ID: 7907640

Claim:
A system in a transmitting communication station to transmit information sufficient to enable a receiving station to synchronize a plurality of clocks at the receiving station to a corresponding plurality of clocks at the transmitting station, the system comprising: a noncommon clock; a modulator module including circuitry to modulate a carrier to contain data for transmission to the receiving station, the modulator module being configured to modulate the carrier with a predetermined pattern in a periodic manner, the period being defined by a predetermined number of cycles of the noncommon clock; and a secondary clock module including a secondary clock which is asynchronous to the noncommon clock, the secondary clock module being configured to obtain comparison data reflecting a comparison between the secondary clock and the noncommon clock, the data being derived from a count of either (i) a number of secondary clock cycles occurring within a predetermined number of noncommon clock cycles, or (ii) a number of noncommon clock cycles occurring within a predetermined number of secondary clock cycles, and provide the comparison data to the modulator module for transmission to the receiving station.
