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.
Claims22
The method of claim 1, wherein the step of decoding further comprises:
- receiving an analog waveform;
- converting the analog waveform to at least one digital waveform
- isolating a specified frequency range from the at least one digital waveform;
- measuring a magnitude of a first plurality of tones within the specified frequency range;
- identifying a subset of the first plurality of tones having the greatest magnitude relative to a remainder of the first plurality of tones;
- measuring a phase of each tone of the subset relative to other tones of the subset;
- generating a relative phase component from the measured phase of each tone of the subset relative to other tones of the subset;
- and
- decoding at least one symbol from the subset of tones and the relative phase component.
A software radio system, comprising:
- a signal receiver configured to receive at least one analog waveform;
- at least one processor configured to isolate a specified frequency range from the at least one analog waveform;
- a correlator configured to measure a magnitude of a first plurality of tones within the specified frequency range, identify a subset of the first plurality of tones having the greatest magnitude relative to a remainder of the first plurality of tones, and measure a phase of each tone of the subset relative to other tones of the subset;
- wherein the at least one processor generates a relative phase component from the measured phase of each tone of the subset relative to other tones of the subset and decodes at least one symbol from the subset of tones and the relative phase component.
A computer readable medium comprising a program for decoding a multi-phase waveform, the program when executed by a processor causing the processor to perform the steps:
- receiving an analog waveform;
- converting the analog waveform to at least one digital waveform
- isolating a specified frequency range from the at least one digital waveform;
- measuring a magnitude of a first plurality of tones within the specified frequency range;

- measuring a phase of each tone of the subset relative to other tones of the subset;
- generating a relative phase component from the measured phase of each tone of the subset relative to other tones of the subset;
- and
- decoding at least one symbol from the subset of tones and the relative phase component.
