20100103993 | Methods and Arrangements in a Digital Subscriber Line Network - The present invention relates to method and arrangements for reducing crosstalk in a DSL system. This is achieved by providing the users in the network with a ghost line, i.e. a virtual line that should reflect the damage to be caused to the remaining users in the network, and that each user allocates the PSDs such that the allocated PSD is optimized against this ghost line. A central agent is adapted to continuously and individually update the ghost lines by collecting a measure indicating the impact of crosstalk from all modems. | 04-29-2010 |
