摘要：The present invention provides strict commercial time synchronization.Transmission information data and N bits data in a PN signal generated from a PNgenerator are transmitted to a downstream station by multiplexing circuit. Then, the

transmission information data and N bits data are demultiplexed by a demultiplexingcircuit into the transmission information data data and the PN signal. An error betweenthis PN signal and a PN signal generated by a PN generator is detected by a timingdetection circuit. The operation timing of the PN generator is corrected corresponding tothis error. The corrected PN signal and the transmission information data are transmittedby a multiplexing circuit to a upstream station. Then, the corrected PN signal and thetransmission information data are demultiplexed by a demultiplexing circuit.

Subsequently, the timing of generation of the PN-signal by the PN generator is shiftedahead by half the time corresponding to the error detected by a timing detection circuitfrom this PN signal and the PN signal generated by the PN generator.
