Matlab code for qpsk modulation and demodulation in matlab

The following Matlab project contains the source code and Matlab examples used for matlab code for qpsk modulation and demodulation.  The QPSK modulation and demodulation technique which is simulated according to theory by matlab programming. The theoretical description of QPSK modulation and demodulation has described in book of "communication system " SIMON HAYKIN.

Amplitude Modulation Matlab Code

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.
