Abstract: 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).

Abstract translation: 提供了一种同步时分双工（TDD）多线多载波数据通信系统的方法。 使用具有不同种子值的公共生成多项式的独特伪随机比特序列（PRBS）建立同步。 由于使用不同种子值产生的PRBS的相关性低，远程单元只能与其预期信号同步，有效地减轻了大带宽超高速数字用户线（VDSL）的远端和近端串扰影响。
