Ah, I got it. I will look into that.
Btw, generally speaking, how is the efficiency the spectrum sensing in gnu
radio? I use the spectrum_sense.py to sense 9M a step and generate 256
bins which takes me nearly 1 second to sense 1M. It is really slow...
you can see why it is slow when you use spectum_sense.py by browsing in this
forum. search for the spectrum sense discussion =)
in my case, i modify the code of fftsink_nongl.py (I cite it in my thesis
and in my coming paper in korea) ..the modification enable me to form an
energy detector spectrum sensor. and it is quite fast (in 0.xx ms). actually
it can be faster if you use faster PC and optimized same part of the code. I
am on my way to do this.. we also currently working on parallel or
simultaneous spectrum sensing with data transmission. therefore, we will
eliminate the constrain on sensing time and all its tradeoff.
