<p>A synchronizing method and device for data transmission using transparent transmission line. At the preceding stage of a transparent transmission line on the transmission side, periodical amplitude modulation is applied to a transmission signal point, or a zero point is inserted to generate a synchronizing signal. In the case of frame synchronization, the power of the received signal is calculated on the reception side of the transparent transmission line, and the synchronizing signal is transformed into a vector using power values mutually different in phase by 90 degrees along the time axis.</p> |
