Abstract:
A multi-carrier transmission system comprising:a central transceiver;a remote transceiver connected to said central transceiver by a cable;a communication channel for communicating between the central transceiver and the remote transceiver via the cable, said communication channel having a frequency bandwidth in which a plurality of carriers, each having a unique carrier frequency being disposed in separate portions of said frequency bandwidth, said communication channel being configured to allow simultaneous asymmetrical upstream and downstream communication by separating upstream frequencies from downstream frequencies; andmeans for allocating a unique carrier frequency of the plurality of carriers for communicating between the central transceiver and the remote transceiver according to a length of the cable between the central transceiver and the remote transceiver where a value of the frequency that is allocated varies inversely with the length of the cable.
