Amplitude and phase-shift keying — or Asymmetric Phase shift keying, (APSK), is a digital modulation scheme that conveys data by changing, or modulating, both the amplitude and the phase of a reference signal (the carrier wave). In other words, it combines both Amplitude shift… … Wikipedia
Phase modulation — (PM) is a form of modulation that represents information as variations in the instantaneous phase of a carrier wave.Unlike its more popular counterpart, frequency modulation (FM), PM is not very widely used. This is because it tends to require… … Wikipedia
