OOK TX & RX VIs

[josephkirmani]

Can any one guide me about OOK TX and OOK RX LabView VIs for USRP 2920 ? I would really appreciate your help in this regards.

Hello josephkirmani,

I do not know of any premade OOK TX or RX VIs that are a part of the NI-USRP’s functions palette or examples. Are you asking for guidance on creating your own OOK TX/RX VI in LabVIEW, or are you referring to some VIs that already exist and which you have downloaded? 

[josephkirmani]

If example VI is available then it is fine for me, but as you already mentioned there are no premade VIs for OOK TX and RX. Actually I need guidance in creating these VIs. Can you please guide me?

Josephkirmani,

Do you have NI Modulation Toolkit installed? If you do, you will be able to use the ASK VIs (for example, the MT Modulate ASK.vi and MT Demodulate ASK.vi) to easily accomplish your goals, and I can help guide you along with this. Otherwise, here is a white paper on OOK RX without the NI Modulation Toolkit, which might be able to guide you along some of the way.

Addtionally, if you do have the NI Modulation Toolkit, you can try installing the NI-RFSG and NI-RFSA drivers (which are not for the USRP), then open up the ASK examples for those drivers and then try replacing the RFSG vis with USRP vis.

Dear Matthew,

I tried replacing the RFSG VIs with USRP VIs but unfortunately for some of RFSG VIs, I did not able to find equivalent USRP VIs? So how can I fix it ?  

[Matt-Bob]

Josephkirmani,

If you are having trouble, I would suggest you take a look at the NI-USRP PSK examples and just switching out the PSK portion to be ASK using the approximate VIs from the Modulation Toolkit which are used in the NI RFSHG and NI RFSA VIs: C:\Program Files \National Instruments\LabVIEW 2013\examples\instr\niUSRP\ModulationToolkitExamples.

Hello,

I am trying to figure this out how to remake ASK to OOK modulation.. I alredy have modulation toolkit installed. Don't you mind to guide me how to make this?

Eleenthil, 

Please create a new thread instead of posting on older threads to increase visibility. 
Did you take a look at the OOK example Matthew linked previously? http://www.ni.com/example/13192/en/

Also, in your new post please add some additional information like what hardware you're using and what you mean by "remake ASK to OOK modulation".

It might be helpful to attach any code or screenshots you may have also if you're running into any specific issues.
