I am using usrp N210 with db SBX, and I do not have any
message wave (or source file). I simply transmit and receive
a sin wave via USRPs (find my graphs attached). I am not
doing any modulation/de modulations.
I need to know the SNR value at the receiver end. I also
want to adjust the signal strength to change SNR. SNR is
signal strength/noise in db. How can I do this?
I see solutions with modulation schemes, but since I
don’t use any modulation, how can it be done without that?
