Abstract:
A line synchronization method in an overlapped spectrum duplex (OSD) system having K pairs of communications lines. Each pair of communications lines includes an uplink and a downlink. The method includes synchronizing downstream synchronization symbols of downlinks in the pairs of communications lines, and separately synchronizing an upstream synchronization symbol of an uplink of each pair of communications lines with a downstream synchronization symbol of a downlink of each pair of communications lines. The method may be applied to crosstalk channel estimation to distinguish near-end crosstalk (NEXT) and far-end crosstalk (FEXT) crosstalk channels when upstream and downstream spectrums are overlapped.

Claim (Index 21):
A transceiver, as a remote transceiver comprising:\n a memory comprising instructions; and a processor coupled to the memory and configured to execute the instructions, which causes the processor to be configured to:\n receive a downstream synchronization symbol from one of a plurality of local transceivers in a vectoring group, the downstream synchronization symbol being transmitted by the local transceiver at a same position as other downstream synchronization symbols from other local transceivers, and each of remote transceivers corresponding to one of a plurality of downlinks in an overlapped spectrum duplex (OSD) system; and \n transmit an upstream synchronization symbol to the local transceiver, the upstream synchronization symbol and the downstream synchronization symbol being aligned at the same position, and each of the local transceivers corresponding to one of a plurality of uplinks in the OSD system.
