y = ammod(x,Fc,Fs,ini_phase) specifies the initial phase in the modulated signal y in radians. y = ammod(x,Fc,Fs,ini_phase,carramp) performs transmitted-carrier modulation instead of suppressed-carrier modulation where carramp is the carrier amplitude of the modulated signal.Examples...
For Amplitude Modulation, it suppose to have carrier amplitude and modulated amplitude. however, the matlab built in function which is ammod, i cannot find which is carrier amplitude. https://uk.mathworks.com/help/comm/ref/ammod.html y = ammod(x,Fc,Fs,ini_phase) ...
The QAM signal waveforms may be viewed as combined amplitude (rm) and phase (ϕm) modulation. As described in Proakis ([2]), the signal waveforms may be expressed as sm(t) = Re[rmejϕmej2πfct] = rmcos(2πfct+ϕm)rm
Modulate random data symbols using QAM. Normalize the modulator output so that it has an average signal power of 1 W. Set the modulation order and generate random data. M = 64; x = randi([0 M-1],1000,1); Modulate the data. Use the'UnitAveragePower'name-value argument to set the ou...
This MATLAB function returns the complex envelope of the modulation of the input message signal, x, using PAM and the alphabet size, M.
z= amdemod(y,Fc,Fs,ini_phase,carramp)demodulates a signal created through transmitted-carrier modulation instead of suppressed-carrier modulation, wherecarrampis the carrier amplitude of the modulated signal. z= amdemod(y,Fc,Fs,ini_phase,carramp,num,den)specifies the numerator and denominator...
