With the rapid development of digital communication technology, pulse code modulation (PCM), as a basic digital signal processing technology, has been widely used in the fields of speech, image and ...

Automatic modulation recognition (AMR) utilizing deep learning has received considerable attention, demonstrating remarkable potential in extracting complex signal features. However, deep ...

The "pulse code" in PCM comes from the telephone company's method of sending a pulse or no pulse down the line. Mu-Law signals typically ride on a single 64 Kbps DS0 channel in a T1 line.

When I wrote about why we should blame our hatred of phone calls on equipment and infrastructure rather than human habits, I talked about the digital-switching infrastructure called pulse code ...

Pulse amplitude modulation (PAM) fluorometer techniques provide unique information on photosynthetic activity of CAM (crassulacean acid metabolism) plants such as the orchid Dendrobium spp. (cv.
