Hi,
    Thanks for your reply. But those link u have attached i had look into it before. But it is not what i want, actually my exercise is download from NI tutorial. But it only runs Constellation Diagram but i need modulation too..My project supervisor mentioned she need modulation instead demodulation. I have downloaded the hardware exercise of Phase Shift Keying modulation for reference but the equipment or VIs needed i did not have. That's why i trying to modify the exercise instead to show modulation and constellation diagram. :smileyhappy:

Hi,

It seems that you have the Modulation Toolkit and they are a
couple of examples that already show how to simulate the PSK modulation and they
also show the constellation. Take a look at the functions used in: ?MT Shifted
PSK demodulation.vi? and ?MT PSK BER vs EbN0 graph [Reed-Solomon coding].vi?
and let me know if they help.


Also as further reference you can take a look at these
tutorials and knowledge bases: <a href="http://zone.ni.com/devzone/cda/tut/p/id/3293" target="_blank">Digital Modulation
Fundamentals</a>, <a href="http://zone.ni.com/devzone/cda/tut/p/id/6722" target="_blank">Modulation
Toolkit Shipping Examples</a> and <a href="http://zone.ni.com/devzone/cda/tut/p/id/5487" target="_blank">OQPSK</a>.
