USRP FSK Modulation and Demodulation

Hi All,

 

I am currently trying to design a low power communications system that uses some form of frequency shift keying to modulate the data. I want to use the USRPs to examine M-FSK, MSK and GMSK in terms of their SNR and BER. Eventually I will want to modulate and send packets of data over the wireless link.

 

I have looked at the example VIs that come with the USRPs and unfortunately there is no Rx example for FSK, only the Tx.

 

I have tried examining the code for the packet-based tx rx example from the link below

However before I do this I want to make sure that if I adapt the code to include FSK modulation it will still work? Was there a reason that only PSK was included? I have included the Tx and Rx VIs I have been working on.

 

I would be grateful for any help/ direction to example VIs.

 

Thanks,

 

Igorina
