Hi All,
In order to calculate the SNR at the receiver, I have generated a QPSK signal, sent it with an USRP through a canal and then received it with another USRP.
So, I have used The "MPSK SNR Estimator" block at the receiver to monitor the SNR values. But values are not correct, I have tried "MPSK SNR Estimator Probe" block, but values still not correct.
I am wondering what is the proper way to use "MPSK SNR Estimator" block? or if there is another block or method to retrieve SNR values correctly? So that I can find correct results.
Any help is appreciated. Thank you.
Best regards,
