Abstract:
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 by a device; (c) identifying where primary intermodulation products formed as a result of signal transmission on said pair of base frequencies fall within said first bandwidth by said device; (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, further comprising the step of adapting said at least one frequency cluster for sending a high priority communication on said at least one frequency cluster or for sending a high bandwidth communication on said at least one frequency cluster.
