CLOCK RECOVERY METHOD AND DEVICE |
摘要 |
A clock recovery method and device relate to the field of communication; and address the problem of the non-synchronization between the sampling clock of the transmitter and the sampling clock of the receiver. The method includes calculating a clock sampling error, a signal phase error compensation value, and a residual phase error compensation value based on data obtained after polarization demultiplexing and equalizing; adjusting a sampling clock based on the clock sampling error; performing phase adjustment for the first time based on the signal phase error compensation value; performing phase adjustment for the second time based on the residual phase error compensation value. The technical scheme provided by the embodiments of the present invention is adapted to a coherent data receiver, and achieve the mechanism of the three levels of error compensation. |
