METHOD AND SYSTEM FOR ONE-WAY TIME TRANSMISSION

摘要

A method of controlling a timing state of a local oscillator (17) being synchronized by a timing signal (ST1) provided through one-way transmission from a remote master oscillator (6) through a dielectric waveguide (4). The method comprises the steps of: receiving (101) a first timing signal (ST 1) modulated on a first electromagnetic carrier having a first carrier wavelength (?1) and transmitted through the dielectric waveguide (4); receiving(101) a second timing signal (ST2) modulated on a second electromagnetic carrier having a second carrier wavelength (?2) different from the first carrier wavelength (?1) and transmitted through the dielectric waveguide (4) together with the first timing signal (ST1); providing(102) a signal (Sdiff) indicative of a difference between a transmission time (T1) of the first timing signal (ST1) and a transmission time (T2) of the second timing signal (ST2) through the dielectric waveguide; and controlling (103) the timing state of the local oscillator (17) based on the first timing signal (ST1)and the signal (Sdiff) indicative of the difference between the transmission time (T1) of the first timing signal (ST1) and the transmission time (T2) of the second timing signal (ST2).
