Common digital modulation techniques include amplitude-shift keying (ASK), frequency-shift ... occur at the zero crossing points. The proper demodulation of BPSK requires the signal to be compared ...

We can pull all that together into an educational model for two SDRs talking to each other, but it’s going to require two parts: modulation and demodulation ... X axis of a graph and Q on ...

[brmarcum] takes us back to analog building block basics with his Frequency Modulation and Demodulation tutorial. Frequency Modulation (FM) sounds simple at first, but understanding the ...

6. In other words, by separately training each CNN to achieve accurate demodulation of its own modulation blocks, we can increase the accuracy of the overall demodulation process. Figure 5 ...
