Hi, I am trying to use "usrp_sprectrum_sense.py" to obtain Idle (white space) and busy cycles of a channel (say channel 1 of WiFi). I was thinking of doing it the following way: Continuously get the FFT (and hence power in db) of center frequency of channel 1. Whenever the power is very low (below a threshold), assume the channel was idle, otherwise channel was busy. Let us say, I found that 10 consecutive fft readings indicated that channel was idle, can I assume that the corresponding idle period was 10xtime to get one FFT reading? Is "time to get one FFT reading" equal to "dwell_delay"? If not, what is its value? If the above method is not accurate/correct, any other method which would work? Thanks -Anirudh

I think that to get one FFT reading shall equal dwell_delay + tune delay -- View this message in context: http://gnuradio.4.n7.nabble.com/obtaining-duration... Sent from the GnuRadio mailing list archive at Nabble.com.
