The following Matlab project contains the source code and Matlab examples used for phase modulation and demodulation.
The Code describes the way to modulate or demodulate a signal shift in its phase.
Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. AM works by varying the strength (amplitude) of the carrier in proportion to the waveform being sent. That waveform may, for instance, correspond to the sounds to be reproduced by a loudspeaker, or the light intensity of television pixels.
