Phase-jitter modulation - Wikipedia
Method[ edit ]
PJM works by representing data as very small phase changes in the instantaneous phase of a carrier signal. PJM can be regarded as a very low-level phase-modulation (PM) signal where amplitude-modulation (AM) components are suppressed to provide a constant-modulus signal. Most of the power (greater than 99%) in a PJM signal is transmitted as an un-modulated carrier and conveys no information. Less than 1% of the transmitted power is used for conveying the modulated data.
Passive RFID tags have no internal power source and derive their power from an external power source,...
