GFSK modulator in Genesys or systemvue

Hi all, I need design a GFSK modulator in Genesys or systemvue. I can't design the FSK modulator I don't know how do it. I guess that basic design is this:

BIT_STREAM (designed)---->GAUSSIAN_FILTER (designed)---->VCO (UNDESIGNED)

BIT_STREAM: Central frecuency= 1MHz
GAUSSIAN_FILTER: Cuttoff_3dB=500KHz
VCO: 1V=+160KHz and -1V=-160KHz

Can someone help me? I'm very desperated.

Thanks for all.

Best regards.

Any idea? someone can tell me any paper where it explains how to design a VCO?

Regards

Thanks you very much, k8ur, for answer. I′ve gone to the web page, but the link to that paper is broken. Can you send me it to my email?

Thanks a lot.
