Frequency domain coding

  • A. D. Houghton


Finite fields are amenable to Fourier transform-like operations which move the data through orthogonal domains in a very similar manner to which the Fourier transform provides a doorway between time and frequency. Just as the Fourier transform extracts pure sine waves from time domain data, the equivalent operation on a finite field extracts features from the time domain data and makes them visible to the observer, although these features are not of course sine waves.
