Dual frequency optical carrier technique for transmission of reference frequencies in dispersive media |
摘要 |
Two different carrier frequencies modulated by a reference frequency are transmitted to each receiver to be synchronized therewith. Each receiver responds to local phase differences between the two received signals to correct the phase of one of them so as to maintain the corrected signal as a reliable synchronization reference.
