The multitone QAM signal is designed by exploiting the non-linearity of the receiver-rectifier, and both amplitudes and phases are used for information transfer offering an advantage of a higher ...
Method: Uses autocorrelation to calculate SNR by measuring the signal peak and noise floor. Determines modulation type (e.g., PSK, QAM) by clustering signal amplitudes and mapping cluster counts.
