[Discuss-gnuradio] SNR or Other Metrics

2013-12-16 Thread Dan CaJacob
I'd like to report some signal metrics for satellite downlinks. SNR would seem to be one example, but most algorithms I see for SNR assume that you are generating a signal from a separate clean signal and noise source, each with known power. What I have are recordings of real, narrow-band,

I often speed up the playback of large recordings by adjusting the throttle only. In the throttle block, I just multiple the recorded sample rate by a factor (say 10) to get increased playback speed. Don't change any other blocks' parameters - just the throttle. Very Respectfully, Dan CaJacob
