Thanks for your reply Bruhtesfa, by subtracting the log of the FFT size, I think I am normalizing the sum to the length of the FFT already. At least this is why I am subtracting the FFT size. In the meantime, I ran into another issue while playing around with a signal generator and my spectrum se

Hi, first of all sorry for the last post, I was too quick with the enter button :-) I am currently working on my final thesis and I really need some help in understanding the correct calculations that are necessary to get usable data out of the FFT values in usrp_spectrum_sense.py. What I need
