Latest Patents

Yujie He holds a patent titled "Crosstalk channel estimation for legacy CPE." This patent describes a digital subscriber line (DSL) network device designed for coupling to DSL communication lines. The device features multiplexing circuitry that transmits signals to both vector-compliant consumer premises equipment (CPE) and legacy CPE. The processing circuitry is configured to initiate the transmission of a predetermined set of orthogonal pilot sequences to multiple vector-compliant CPEs. It also initiates the transmission of data symbols corresponding to these sequences to one or more legacy CPEs. Furthermore, the device pre-processes line errors of a victim vector-compliant CPE to eliminate far-end crosstalk caused by vector-compliant disturber lines. It determines far-end channel crosstalk information through correlation of pre-processed line errors and transmitted data symbols, ultimately reducing far-end channel crosstalk for the victim vector-compliant CPE.
