  • Method of synchronizing a communication system
    Patent number: 9306733
    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).
    Type: Grant
    Filed: November 27, 2013
    Date of Patent: April 5, 2016
    Assignee: BROADCOM CORPORATION
