Figure 1c shows the simplified discrete phase map using this two-level amplitude modulation. The blank areas indicate pixels without antennas.

In this report, we introduce our demodulation method using AI (Artificial Intelligence) for realization of a multi-level amplitude recording system.

There are two radio modulation schemes everyone should know. Amplitude modulation changes the amplitude — or ‘volume’, if you will — of a carrier frequency and turns all rad… ...
