Re: [Discuss-gnuradio] [USRP-users] Measuring Input SNR in USRP using On-Off Keying modulation

[Colby Boyer]

One method would be to use a single pole IIR filter to get an average of the noise floor energy, and compare that with the average symbol energy.

Hello all,

Lately, I am experimenting with a point-to-point SDR link where my transmitter uses On-Off Keying modulation while the receiver follows techniques for efficient signal processing and detection (non-coherent, coherent). My major problem is how can I measure the input SNR as a ratio of the power of the received signal to the power of noise, given also that we ignore the quantity of NF (Noise Figure).

Thank you in advance for your concern,

GS
