METHOD AND APPARATUS FOR CONFIGURING VIRTUAL NOISE PARAMETERS OF VERY HIGH SPEED DIGITAL SUBSCRIBER LINE |
摘要 |
<p>An apparatus comprising a transmitter configured to transmit a digital subscriber line (DSL) signal in a line from a plurality of subscriber lines according to a reference virtual noise power spectral density (PSD), wherein the reference virtual noise PSD is based on an upper bound for a worst-case far-end crosstalk (FEXT) PSD in the subscriber lines. Also included is an apparatus comprising at least one processor configured to implement a method comprising obtaining an upper bound for a worst-case FEXT PSD for a plurality of subscriber lines, obtaining a referred virtual noise PSD based on the worst-case FEXT PSD for the lines, and determining a bit-loading for the lines based on the referred virtual noise or a scaled version of the receiver-referred virtual noise.</p> |
