This is our conversation from last month:"I am trying to design a
cognitive radio. I have already designed an energy detector as part of spectrum
sensing and now I am trying to implement spectrum management. So, I need to
transmit a signal at those sections of the frequency spectrum where the
threshold block outputs a zero value. Basically I need to link the output from
the threshold block from the energy detector flow graph with that of the USRP
source such that the USRP transmits at a frequency where the threshold block
outputs a zero value. Is there a way to do this ?"The above is the
question that I asked to which you replied as follows:"Yes, there are ways
to do this, but you'll have to come up with some approach of an application
you want to do that way. You say you've implemented an energy
detector, so I guess you're already familiar with the Guided
Tutorials[1]?"After this I replied:"Yes, I am familiar with the
guided tutorial
s. I don’t understand what you meant when you said that I’ll have
to come up with some approach of application from my side.If there are a number
of ways, then please describe the best possible way solve this problem."
