I have verified the Matlab code in a QPSK modulation system with a similar
one that is built on simulink. The BERs matched :)
Have obtained the paper too.... 26 pages! Will certainly try to read it.
Thks Andor.

I guess that kind of depends how non-1/f the noise model is. You should
also find a link to the following paper
N. J. Kasdin, "Discrete Simulation of Colored Noise and Stochastic
Processes and 1/f^a Power Law Noise Generation," Proceedings of
the IEEE, May, 1995.
It is a nice read. If you still have questions after that, come back
here.

Hi Andor,
Thank you very much for pointing out the link. I will try that out
first thing next morning.
I note that the Matlab code models a 1/f noise model. If a specific
non 1/f noise model is to be modelled, is there a way to do it?

kc

If you search comp.dsp with the phrase
"simulation of 1/f noise"
you will find a link to an old post which contains Matlab code to do
just that.
Regards,
Andor

Hi.
I am trying to model oscillator phase noise using Matlab m-code. I know
there is a phase noise blockset in the simulink. I looked under the blockset
mask and learnt that the phase noise is modelled by passing AWGN noise
through a direct form II transposed (DF2T) filter whose shape is probably
1/f. If given another type of frequency response of a phase noise model, how
do I generate the filter coefficients for the DF2T filter?
Is the Matlab function 'Yulewalk' sufficient to generate these filter
coefficients?
Thanks!
