    Abstract
    This paper presents a simple digital signal modulation/demodulation technique for the purpose of radiofrequency (RF) communications that involves the control of smooth phase amplitude oscillations within a carrier signal. The technique falls under the category of phase-shift keying (PSK) yet is distinctly different from existing PSK techniques. Identification of digital states is achieved via discernment between discrete combinations of off-centre side-lobes about the primary line profile of the carrier spectrum (ala discrete oscillator phase noise), with side-lobes being a function of the above phase amplitude oscillation. ...

    This paper presents a simple digital signal modulation/demodulation technique for the purpose of radiofrequency (RF) communications that involves the control of smooth phase amplitude oscillations within a carrier signal. The technique falls under the category of phase-shift keying (PSK) yet is distinctly different from existing PSK techniques. Identification of digital states is achieved via discernment between discrete combinations of off-centre side-lobes about the primary line profile of the carrier spectrum (ala discrete oscillator phase noise), with side-lobes being a function of the above phase amplitude oscillation. For a 2.4 GHz carrier signal, technique variants theoretically allow for competitive data transmission rates of 3 to 8 Mbit/s, which are extendable with variant expansion. Technique robustness (in relation to cryptographic security and resilience towards interference and distortion) is a consequence of amplitude fluctuation immunity, self-referencing at demodulation, smooth waveform transitions between states, single RF source control, and highly distinguishable output states for modest changes in the relevant phase-based modulation parameter.
