Method of synchronizing a communication system

摘要

A method of synchronizing a time division duplex (TDD) multi-line, multi-carrier data communication system is provided. Synchronization is established using unique pseudo-random bit sequences (PRBS) from a common generator polynomial having different seed values. Due to low correlation of PRBS generated with different seed values, a remote unit can only synchronize to its intended signal effectively mitigating far-end and near-end crosstalk impact of large bandwidth very high speed digital subscriber lines (VDSL).

1. A method for synchronizing communication signals, the method comprising:
generating n unique seed values for n remote units; assigning, for the n remote units, a corresponding one of the n unique seed values to a corresponding one of the n remote units; transmitting from a central unit to the n remote units the corresponding assigned one of the n unique seed values; constructing unique pseudo-random bit sequences for each of the n remote units using the corresponding assigned one of the n unique seed values and at least one pseudo-random bit sequence generator polynomial; and transmitting the unique pseudo-random bit sequences to corresponding n remote units for the synchronization of the communication signals.
