BPSK modulator and demodulator

[andre.labview]

I'm new to labview (2017) and I'm trying to implement a basic BPSK modulator and demodulator VI.
I need to compare 2 channel: the first one must be ideal channel and the second have to contain white Gaussian noise.
Can you explain me why it doesn't work?

I've already searched in other thread but I can't find something useful for my problem. Thanks for all your answers
I have another question: Several example can't be opened on my computer. can you explain me how to solve it?
thanks for all
Andrea

Hi 

Your code is not easy to debug and probably it contains unusefull part, I suggest you to see the code in this forum post and try to start from that one: https://forums.ni.com/t5/Example-Programs/BPSK-Example-in-the-Real-Plane/ta-p/3527237
