Hello,
i have the phase noise characteristics of vco in matlab. I want to transfer this to simulink for further processing. Does anybody have an idea that how it can be done?
Thanks

Describe in detail.

What characteristics do you have ?

Frequency Domain Data such as Noise PSD ?
Time Domain Data such as Jitter ?

Can you understan "Equivalent Lowpass Model" ?

I want to use this phase noise characteristics in simulink.

Simulink is a time-domain simulator.

You have to shape white gaussian noise by filter.
Here you have to generate noise_phase(time) or "noise_I(time) and noise_Q(time)".

Again can you understand "Equivalent Lowpass Model" ?

what is Equivalent Lowpass Model?

yes, I understand this model but I have problem that I don't know how to add the phase noise of VCO in the model

Output of Phase Domain Model is phase.
So Simply add phase noise(time) to output of Phase Domain Model.
