Claim 0:
1. A data, communication method, the method comprising:
receiving input digital data;
encoding the input digital data into an encoded waveform representative of the input digital data wherein the encoded waveform is of a wavelength λ and wherein each period of the encoded waveform includes a first half sinusoid corresponding to one half of a first sinusoid of wavelength λ1 and a second half sinusoid corresponding to one half of a second sinusoid of wavelength λ2, where λ1+λ2=λ, and where one of λ1 and λ2 is higher than λ and the other one of λ1 and λ2 is lower than λ, the encoding including generating each period of the encoded waveform so as to represent one bit of the input digital data;
wherein the first half sinusoid is of a first polarity and the second half sinusoid of a second polarity opposite to the first polarity;
wherein a first bit value of the input digital data is represented when λ1 is greater than λ2 and a second bit value of the input digital data is represented when λ2 is greater than λ1;
wherein each period of the encoded waveform is represented by a function T(t), where T(t) is given by:, T
