what is that 20KHz?
--- Quote End ---
The frequencies for the fsk messagge are in the range 3Khz to 20Khz, so for example a message could be modulated with 4050 for F0 and 4450 for F1 and another message could be modulated with 18000 for F0 and 18400 for F1.

baud = 200, can't be

the data baud rate is up to 200baud (i.e. from 40Hz to 200Hz)

IQ demod outputs:
IQ demodulator downconverts to what values for f0,f1
you will need to filter the second sideband on each of I and Q after downconversion. So you need to tell us what is f0,f1 after IQ demod and what is sampling rate.

I think i need 2 iq demodulator one for F0 freq and another for f1 signal,is it right?
At the moment the sampling rate is 200khz...
The last question is not so clear...
