    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 document is adapted to a coherent data receiver, and achieve the mechanism of the three levels of error compensation.

    摘要: A system has a first transmitter for transmitting a first wireless signal within a first frequency. A second transmitter is for transmitting a second wireless signal with overlapping frequency. The first transmitter and the second transmitter are disposed sufficiently proximate to another such that the wireless signals substantially interfere resulting in a combined wireless signal with negative SNR for each of the first wireless signal and the second wireless signal, the negative SNR being a result of at least the other of the first wireless signal and the second wireless signal. A receiver is located for receiving a received wireless signal comprising substantially interfering encoded data signals having negative SNR. The receiver is for selecting from the substantially interfering encoded data signals a signal of interest and for decoding said signal of interest relative to at least the other substantially interfering data signal within the received wireless signal.
