摘要: A method of recovering information encoded by a modulated sinusoidal waveform having first, second, third and fourth data notches at respective phase angles, where power the is reduced relative to an unmodulated within selected ones so as encode input digital data. The includes receiving generating values representing waveform. representation subtracted from in order generate received sequence, which notch representative amplitude notches. then estimated based upon values.
