Problem with 2x2 MIMO with Alamouti Coding

[zhenghao]

Hi 

I am trying to get a MIMO system with 2 NI-USRP 2901 running.

When I was trying to run the project, I had problems like that

I can't find Modulation Toolkits 4.3.1 online and I am using 19.0 instead. Do I have to use the version recommend or this is some VI files missing in the zip file.

I would my pleasure if someone can answer this question.

Best
