Synchronization of remote clocks

摘要

A method and a clock distribution node arranged to synchronize one or more remote clocks with a local clock. The clock distribution node calculates a first time offset between the local clock and the remote clock from an interference pattern between a spatially aligned local pulse sequence from the local clock and remote pulse sequence from the remote clock; receives a second time offset from a remote node; and applies a time offset value based on a difference between the first and second time offsets to the remote clock to synchronize the remote to the local clock, wherein the remote node is arranged to calculate the second time offset based from an interference pattern between a spatially aligned local pulse sequence from the local clock and remote pulse sequence from the remote clock.
