ABSTRACT:
A method for non-orthogonal frequency division multiplexed communication through a non-linear transmission medium includes the steps of selecting at least one desired bandwidth, selecting a non-orthogonal pair of base frequencies within a first bandwidth of the at least one desired bandwidth, identifying where primary intermodulation products formed as a result of signal transmission on the pair of base frequencies fall within the first bandwidth. The method may also include the step of selecting a plurality of non-orthogonal interleaved frequencies adjacent at least one of the pair of base frequencies so as to be interleaved between the primary intermodulation products to form a frequency cluster which includes the at least one of the pair of base frequencies and the interleaved frequencies.
