Hi,
Can anyone explain how do we calculate SNR from the received USRP
samples(complex/float).
Thanking You,

It depends rather a lot on what kind of *signal* you're trying to
demodulate, which is where SNR measurements
come in.

Hello Swapna,
The SNR in wireless channel cannot be measured but it can be "estimated". One
way to do that for constant envelope modulation such as PSK is by measuring the
variance in the received signal envelope. Ideally you should receive a constant
stable envelope of your signal. However, du
I am sorry if my previous mail was confusing. I am trying to switch toa
different Rx freq depending on a control information. Even though I exit
from rx_callback and try to call a new script for Rx using os.system I get

Eric,
Thank You.
os.system() worked. I can now switch between different scripts while in
transmitting mode.
To all,
While receiving data (using a modification of benchmark_rx.py) I need to
receive at a different frequency depending on some control information .
I get an error message while attem
