Abstract: Method for communication channel coordination between nodes, each node including at least one of a transmitter and a receiver, for transmitting and receiving signals over residential electrical cables. The residential electrical cables include at least one active wire, one neutral wire and one ground wire, at least two of the wires forming wire pairs. The method includes the procedures of, for a given one of the receiver, examining the transmitter in each one of the nodes which communicates with the receiver, selecting one of the examined transmitters as a primary transmitter, determining an optimal receive wire pair for the receiver to receive the signals transmitted between the primary transmitter and the receiver, informing all the examined transmitters of the determined optimal receive wire pair, and tracking at least one communication characteristic over the determined optimal receive wire pair.

Abstract: A method for conveying digital data from a transmitter (20) to a receiver (40) includes specifying a spectral filtering profile to be applied in conveying the data. A sequence of input symbols is generated (22) at the transmitter, corresponding to the data to be conveyed. The input symbols are precoded at the transmitter using Tomlinson-Harashima precoding (25) responsive to the specified profile, so as to generate a corresponding sequence of precoded symbols. The precoded symbols are filtered (26) in accordance with the specified profile. The precoded and filtered symbols are decoded at the receiver so as to recover the data therefrom.

Abstract: A method is provided for initiating communications over a channel between a transmitter and a receiver within a specified spectral range, subject to a mask to be applied at the transmitter so as to attenuate at least one segment of the spectral range. The method includes providing to the receiver a definition of the at least one segment and of a level of attenuation to be applied within the at least one segment during a training interval of the communications. A training signal is transmitted from the transmitter to the receiver while applying to the training signal the level of attenuation within the at least one segment. The receiver compensates for a response of the channel based on the received training signal and on the definition of the at least one segment and of the level of attenuation.

Abstract: A high-speed transmitter, which generates an output signal stream having a specified spectral profile. The transmitter includes a Tomlinson-Harashima precoder, which is adapted to receive a sequence of input symbols having a given input constellation and to generate, responsive to the specified spectral profile, a corresponding sequence of precoded symbols. A transmit digital filter is adapted to apply a transmit filter response, in accordance with the specified spectral profile, to the precoded symbols so as to generate a corresponding sequence of output symbols, having a given output constellation, to be transmitted in the output stream.
