A new publication from Opto-Electronic Advances, 10.29026/oea.2023.220157 discusses lensless complex amplitude demodulation based on deep learning in holographic data storage.

4.3 Results: Demodulation of four-level amplitude-modulated data. We next compare the demodulation performance of our CNN approach to results obtained via conventional hard-decision methods.

MSD 101: Demodulation. Aug. 1, 2002. ... But because of the short duration and low amplitude of impact events, there isn’t energy for their peaks to stand out individually.

The theoretical requirements for demodulating AM signals with asymmetrical sidebands are outlined. A novel form of demodulator is described which makes use of the variation in the phase of the ...
