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 1):
A line synchronization method comprising:\n synchronizing a plurality of downstream synchronization symbols from local transceivers, in a plurality of pairs of communications lines, at least in part by configuring a plurality of local transceivers in a vectoring group to cause the downstream synchronization symbols to be at a same position, each of local transceivers corresponding to one of a plurality of downlinks in an overlapped spectrum duplex (OSD) system; and synchronizing upstream synchronization symbols with the downstream synchronization symbols at least in part by configuring a plurality of remote transceivers in the vectoring group to cause upstream synchronization symbols from the remote transceivers and the downstream synchronization symbols to be at the same position, each of the remote transceivers corresponding to one of a plurality of uplinks in the OSD system.
