Pulse Amplitude Modulation & Demodulation – Application in MATLAB

pamdemod Pulse amplitude demodulation [1] Syntax z = pamdemod(y,M) z = pamdemod(y,M,ini_phase) z = pamdemod(y,M,ini_phase,symbol_order) Description z = pamdemod(y,M) demodulates the complex envelope y of a pulse amplitude modulated signal. M is the alphabet size. The ideal modulated signal should have a minimum Euclidean distance of 2. z = pamdemod(y,M,ini_phase) specifies the initial phase of […]

Modulation in MATLAB

This part is regarding acquiring information for the modulation process of a WAV file saved on the computer’s memory to be modulated using MATLAB, taken directly from online help documentations: http://www.mathworks.com/access/helpdesk/help/toolbox/comm/ug/fp59183.html Modulation [1] in MATLAB In most media for communication, only a fixed range of frequencies is available for transmission. One way to communicate a […]
