USRP Intergration to a system with loops

[HUSAM2324]

Hi everyone,

I am new to USRP and LabVIEW. I have an OFDM system where I merged the transmitter and receiver sides together, and I am trying to integrate USRP into it. The system works without the USRP, but when I integrate it, only the transmitter side works, and no signal reaches the receiver side (it doesn't work). LabVIEW sometimes gives me the error shown in the picture below. I have also attached the VI file of the program. Any help would be appreciated.

Your two inner while loops run in sequence (not in parallel) due to a wired data dependency. Is that what you want?

I don't understand your code architecture and the need for that pyramid of FOR loops while there is no toplevel while loop or any recognizable state machine architecture)

Hi Knight of NI,

thank you for your help

this is a normal OFDM system. I just add the FOR loops to calculate the BER of the system and I also add the transmitter and the receiver together. Now, I want to make the system work simultaneously, like when I use the transmitter and receiver separately. As for the while loops, I removed them, but the system still doesn’t work. I removed the wire you mentioned, and the receiver started working. Now, I’m trying to send the information that I was previously sending with a wire through the USRP, but I got an error saying that I have connected two clusters with different contents.

I attached an example I found about how to calculate the BER. and also here is OFDM system l looked at Streaming OFDM Transmitter and Receiver - Page 2 - NI Community
