Dear all,

I am trying to simulate the phase noise on Matlab using only gaussian noise. What I expect is that, interms of the signal (eg. sinewave) it shifts in phase due to noise.
For that I don't need the awgn on top of the signal, but the signal itself with the noise built-in.

Best regards,
Pedro
 

Hi Pedro,

The noisy perturbation must be in the argument.
In the case you are generating a sine wave:

noisless: x=sin(omega*t);
noisy: x=sin(omega*t+sigma*randn(size(t)));

Is that your situation?
Regards

Hi,

Thanks for your answer. Well, I wanted to use awgn function, but to modulate it into the signal.

Best regards,
Pedro
