You may find this example on DPSK helpful as it calculates BER in a fashion that you might be looking for: http://www.ni.com/example/30126/en/
As well, you can look up some more information on usage of the Modulation Toolkit's BER VIs with this help page (even though its targeted for LabVIEW Comms, it has a similar implementation in regular LabVIEW): http://www.ni.com/documentation/en/labview-comms/1.0/mt-node-ref/mt-calculate-ber/
Thanks for your reply
These examples are concerned about simulation. Where do I find BER Examples that use USRPs
As an aside, there are multiple forum threads and posts about this same question and unfortunately the answer is that right now there is no explicit example that just calculates BER. BER and its calculation is very dependent on your modulation and demodulation scheme, so I would suggest you explore how you would calculate BER mathematically given your specific scheme and then work with Modulation Toolkit to implement this.
hey friend, did you find out the way to do ber? I got the same question as you do. just use basic bpsk, then I want to see the ber. thank you.
hey, friend. Check this link. It seems that this guy did the ber right, but he want to do something more, and he failed. please let me know what you think? because I am working on ber as well. thank you.
My friend, I also post something about the ber problem. if you have any updates, please give me a reply here. thank you!
