Abstract
A digital encoding system for encoding a series of input bits into a plurality of frequencies, includes an encoder for generating a sampled representation of the frequencies corresponding to an input data sequence comprised of bits, and a decoder. The decoder incorporates a Fourier Transform means for recovering the data stream.
Claims1
A method comprising:
- a) encoding of bits with a plurality of frequencies within a window represented by Ns samples
- b) where Ns=Fs/fmin=windowed data
- c) Fs>2fmax
- d) M possible frequencies=fmax−fmin
- e) Total possible bits is related by M frequencies times N windows.
