Cognitive radio systems must robustly sense spectrum holes if they want to use spectrum opportunistically. A traditional sensitivity based time-domain perspective on this sensing problem is relatively straightforward and such sensitivity based sensors are easy to certify. However, this problem is more subtle than it first appears. To really understand the question of {\em what should be the right level of sensitivity for a sensor?}, especially for multi-user sensing algorithms, one is forced to… CONTINUE READING
