Received Signal Power

GNU Radio
1

Hello,

I have transmitted and received signal using USRP board. I can see the
received power spectral density by using WX GUI FFT Sink. How can I find
the received power of a signal? I mean I don’t require power spectral
density but I need the received signal power.

I highly appreciate your reply.

The power of a signal over its bandwidth is computed as:

AVG(II+QQ)

Average/Decimate/SQRT to taste.

Use complex_to_maq_squared, integrate with decimate, then 10*log() + K,
and
into a time sink or signal probe. K is a calibration factor in dB that
you
obtain by feeding your hardware with a known power level, typically a
signal
generator.
