A method and apparatus for reducing the strength of interference (e.g., crosstalk noise and/or echo interference) in multicarrier communications. Carrier subchannels are selected from a plurality of carriers having a range of frequencies. The carrier subchannels are selected by first selecting a first subset of the plurality of carriers, spanning a frequency range having a highest frequency end and a lowest frequency end. Each subchannel in the subset can carry a signal of at least one bit. At least one of the carrier subchannels of the subset for transmitting one or more bits of the digital signals is allocated at one of the ends of the frequency range. Input digital signals are modulated on to the carrier subchannels, are transmitted and received and are demodulated as output digital signals. Carrier subchannels are used in such a way as to reduce or minimize the magnitude of interference phenomena, including near end crosstalk, far end crosstalk, echo, and noise, when transmitting digital signals. |
