Phase Shift Key : Modulation toolkit

[ade77]

I am trying to simulate a phase shift key, I followed one NI example. the example worked fine, and I used the same code but my didi not work. The number of symbol is not correct.

I have attached the VI , I could not figure out what the problem was. The constellation graph should remain constant, rather that moving , and the number of symbol in the graph should be equal to the number of symbol on the control.

Thanks for any help.

Hello ade77

Thanks for your post. It looks like your  Eb/NO (10 dB) value is not high enough to get the right number of symbols in the right place. Try increasing this number and see if that helps. See the screen shot of your code attached. 

Let us know if this helps!

Cheers!

You say you are unable to do something and want help.  But you don't say what your problem is and what kind of help you need.

Please start a new thread.  Tell where you are having problems.  Post any VI's that you have started working on.  Ask specific questions about your problem.

Then it would be possible for someone to be able to help you.
