How can I combine the IQ signal with the AWGN signal?

[oyw1022]

I have USRP2921 and LabVIEW NXG.

I'd like to mix IQ signals with AWGN signals, but I don't know how to mix AWGN signals with IQ signals.

 So I need professional help.

What is the desired result of the "mix"?

It would also help if you post some code. What are those signals? What is their frequency, size, data type? And is that the same for the IQ and AWGN signal?

I want to mix AWGN signals with IQ signals generated by Tx, and I want to read the mixed signals from Rx and compare performance with filters supported by LabVIEW.

But I have a problem.
1) I don't know the difference between IQ rate and Sampling rate.

2) The array of AWGN signals and arrays of IQ signals are different.

3) I'm not understand the flow and structure of this signal. 

So I need your education.

Hello, I have just seen your post and I have the same problem with you. Do you know how to solve it now? may I know it?

Thank you in advance
