A Unified Approach for Probability of Detection Evaluation over Generalised Fading Channels
(Institution of Engineering and Technology, 2016)
In this paper, we revisit energy detection-based spectrum sensing cognitive radio systems operating over generalised fading channels. In particular, we derive closed-form exact expressions as well as lowand high-signal-to-noise ...
Spectrum Sensing Via Reconfigurable Antennas: Fundamental Limits and Potential Gains
We propose a novel spectrum sensing technique in cognitive radio networks that provides diversity and capacity benefits using a single antenna at the Secondary User (SU) receiver. The proposed scheme is based on a ...
