| 摘要 |
The present invention relates to a vectoring controller (130) for controlling a vectoring processor (120) that mitigates crosstalk between communication lines (L1..LN) of a vectoring group. In accordance with an embodiment of the invention, the vectoring controller is adapted to iterate through successive crosstalk acquisition cycles and, within respective ones of the crosstalk acquisition cycles, to configure sequences of crosstalk probing symbols for transmission over the respective communication lines, to receive sequences of error samples as successively measured by respective receivers (110, 210) coupled to the respective communication lines while the sequences of crosstalk probing symbols are being transmitted, and to determine crosstalk estimates between the respective communication lines based on the sequences of error samples. The vectoring controller is further adapted to randomize the successive sequences of crosstalk probing symbols used during the successive crosstalk acquisition cycles, and to iteratively configure the vectoring processor based on the successive crosstalk estimates. The present invention also relates to a method controlling the vectoring processor. |
