Galen,
You raise a very important point. There are a lot of other systems that are
sensitive to RF but not RF transmitters. Any new use of spectrum really
should try to foresee and avoid those impacts.
We had a major 'train wreck' in this area in the mid-90's when cellular went
digital.

First of all, what you're describing is barely cognitive; you want to
look at the momentaneous power in a subchannel, and transmit only when
it's free. That principle is simply known as Car
likely render those frequencies
unusable for their purposes.
I'm not attacking but hoping to raise awareness.

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]?

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. Basica
