Patent ID: 8199779

Claim:
A system in a transmitting communication station to transmit information sufficient to enable a receiving station to synchronize one or more clocks at the receiving station to one or more corresponding 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 and provide the comparison data to the modulator module for transmission to the receiving station, wherein the comparison data is derived from a number of noncommon clock cycles occurring within a predetermined number of secondary clock cycles.
