Abstract
Disclosed are various embodiments of systems and methods for relative phase shift keying. In one embodiment, an analog waveform is converted to digital signals. A specified frequency range is isolated and the magnitudes of tones corresponding to a channel are measured. The relative phase of a subset of the tones having the greatest magnitude is measured and a relative phase component is generated. At least one symbol is associated with the subset of tones and the relative phase component.
