Description: On the Energy Detection of Unknown Signals Over Fading ChannelsAbstract—This letter addresses the problem of energy detection of an unknown signal over a multipath channel. It starts with the no-diversity case, and presents some alternative closed-form expressions for the probability of detection to those recently reported in the literature. Detection capability is boosted by implementing both square-law combining and square-law selection diversity schemes. Index Terms—Diversity schemes, energy detection, fading channels, low-power applications, square-law detector, unknown signal detection. Platform: |

Description: In this paper, author consider
cooperative spectrum sensing in order to optimize the sensing
performance and focus on energy detection for spectrum sensing
and find that the optimal fusion rule is the half-voting rule.
Next, the optimal detection threshold of energy detection is
determined numerically. Finally, we propose a fast spectrum
sensing algorithm for a large network which requires Platform: |
