The system includes at least two power line modems, each one of the two power line modems including a processor, transmitters and at least one receiver, transmitters and the receiver being coupled with the processor, for respectively transmitting and receiving the signals. At least two of the wires form at least one receive wire pair and at least two of the wires form at least one transmit wire pair. Each one of the transmitters defines a respective carrier wave range over the transmit wire pair, the processor determining a frequency carrier wave for the signals when the signals are transmitted. A given one of the transmitters transmits the signals if the frequency carrier wave is in the carrier wave range of the given one of the transmitters.

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