I seen this paper before, and I think what they do is chop up the large bandwidth into smaller channels, so they design a channelized front end. But this is narrowband in nature I believe....just a whole bunch of narrowband channels. That is why the sensitivity and dynamic range can be so good.
Is there another way to do this other than to use a channelized reciever? What happens when I build a front end capable of receiving a 5GHz bandwidth? 10GHz?
See...now using the same equations for senstivity and dynamic range, the values are much worse, maybe even laughable.
So..that's the question........
Thanks for the responses though, they are helpful in this discussion.
