Sensing Performance of Energy Detector With Correlated Multiple Antennas
Sungtae Kim, Jemin Justin Lee, Hano Wang, Daesik Hong · IEEE Signal Processing Letters · 2009
This paper describes the derivation of detection and false-alarm probabilities for energy detectors in cognitive radio networks when a sensing node of the secondary system has correlated multiple antennas. The sensing performance degradation due to the antenna correlation is then investigated based on the performance analysis. The conclusions of the analysis are verified by numerical simulation results.
