Question about Spectrum Sense codes

GNU Radio
1

Hi,
I’m currently working on a project about spectrum sensing and I went
over
the USRP_Spectrun_Sense codes. But I’ve got a question about the content
of
m.data. Because in the while loop, when you print out m.data, it’s
FFT_Size
of samples for each center frequency(Not a single value). If I want to
get
the FFT result for each FFT bin, is it correct to do like this: print
m.center_freq sum(m.data) in each loop. Any help would be appreciated.

Regards,

Chen Dong

Hi Chen,
I was also doing the same as you asked. Since energy equals the sum of
all
FFT coefficients hence summation of all FFT bins looks reasonable to me.
