1. A method for non-orthogonal frequency division multiplexed communication through a non-linear transmission medium, the method comprising the steps of:

  • (a) selecting at least one desired bandwidth;

    (b) selecting a non-orthogonal pair of base frequencies within a first bandwidth of said at least one desired bandwidth;

    (c) identifying where primary intermodulation products formed as a result of signal transmission on said pair of base frequencies fall within said first bandwidth;

    (d) selecting a plurality of non-orthogonal interleaved frequencies adjacent at least one of said pair of base frequencies so as to be interleaved between said primary intermodulation products to form a frequency cluster which includes said at least one of said pair of base frequencies and said interleaved frequencies.
