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.

[Craig] thought it would be fun to build an analog BPSK31 demodulator and hit upon the idea of doing this with amplitude demodulation. No, this isn’t the way you’re supposed to do it, but it ...

But when an impact occurs, its amplitude is modulated; in other words, it rings more loudly. (On a bearing, a roller hitting a fault acts as a striking gong; the bearing acts as the bell.) ...

The most important component of any lock-in amplifier is the demodulator that performs very narrow-band filtering of the signal of interest around a specific frequency. As a result of this ...

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.

This article investigates the demodulation capabilities of a DSSSsuper-regenerative receiver. Starting from the general expressionthat characterizes the receiver's behavior, we demonstrate that afew ...
