Adding same (fully correlated) Phase-noise to two LO paths

Dear All,

I have 4 LO paths (LO0, LO90, LO180 and LO270)  with 25% duty cycle clock output wave forms.

These wave forms are almost squarish and captured form another LO generation circuit simulation.

Currently, I using the captured files of the 4-waveforms for PSS/Pnoise simulation of the receiver circuit.

I want to add  phasenoise to the 4 LO paths.  I have a phase-noise profile file.

But, the important thing I want is :- The phasenoise of LO0 and LO180 should be completely co-related and the phasenoise of  LO90 and LO270 should be completely co-related.

How this can be achieved.

Could anybody please help in this regard.

Kind Regards,
