Abstract: A device for mitigating effects of impulse noise on data packet transfer over a communication line is configured at least partially according to physical layer characteristics of the communication line. As an example, a data packet retransmission device might be configured to retransmit in response to each retransmission request an amount of data packets depending on the physical layer interleaving delay ID and/or data bit rate DBR.

Abstract: A method for determining at least one operational transmit power Snk over a communication channel (Ln) coupled to a disturbance causing transceiver (n) for at least one tone (k), comprises the steps of provision of at least one reference victim communication channel (Lref) for representing at least one reference victim for all victim communication channels which are degraded by cross-talk interferences by said communication channel (Ln), and maximizing the data rate (Rref) over said at least one reference victim communication channel (Lref) under the constraint that the data rate over said communication channel (Ln) achieves a target rate (Rntarget) without exceeding a power constraint (Pnmax).

Abstract: The physical layer session resource broker (PHY SRB) according to the invention receives request from application servers (VOD SERVER, TV BRDCST SERVER, GAME SERVER, WEB SERVER) which are translated into physical layer parameter values. The physical layer parameter values are imposed on the access nodes (DSLAM) by the physical layer session resource broker (PHY SRB).

Abstract: A power control method for transceiver units conveying data over discrete tones. The method includes the steps of: determining a transmit power over a physical channel for each individual tone, such that this transmit power maximizes a weighted function of data rates achievable with this tone over the physical channel and over modeled neighboring channels, with the constraint that this transmit power conforms to a transmit power mask, summing up the data rates over the whole set of tones, adjusting the weights such that the total data rates over the modeled neighboring channels reach some target data rates, and such that the total data rate over the physical channel is maximized, with the constraint that each weight is identical over the whole set of tones.

Abstract: A device (112) for mitigating effects of impulse noise on data packet transfer over a communication line (102) is configured at least partially according to physical layer characteristics of the communication line (102). As an example, a data packet retransmission device (112) might be configured to retransmit in response to each retransmission request an amount of data packets depending on the physical layer interleaving delay ID and/or data bit rate DBR.

Abstract: A method to provide cross-talk cancellation in a multiple input multiple output system that comprises a plurality of outputs is described. The method comprises a step determining during a first phase and according to a heuristic model, for a first signal to be transmitted to a first output of the plurality of outputs at least one dominant interfering tone of at least one second signal to be transmitted to a second output of the plurality of outputs. The at least one dominant interfering tone is in fact a tone of at least one second signal that would generate cross-talk upon the first signal when it would be transmitted to the first output. The method further comprises a step of executing a step of partial cross-talk cancellation for the first signal during a second phase for the one or more determined dominant interfering tones associated to one or another second signal.
