Efficient collaborative spectrum sensing under the smart primary user emulation attacker network
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, collaborative spectrum sensing to detect random signals corrupted by Gaussian noise in the presence of Primary User Emulation Attackers (PUEAs) is studied. We consider smart PUEAs which aims at increasing ...
Correlated Multiple Antennas Spectrum Sensing under Calibration Uncertainty
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
We address the problem of spectrum sensing in cognitive radios (CRs) when the secondary user (SU) is equipped with a multiantenna receiver. We consider scenarios with correlation between the received channels at different ...
Optimization of collaborative spectrum sensing with limited time resource
(
Springer Verlag
, 2015 , Conference Paper)
In this paper, Cognitive Radios (CRs) collaborate in spectrum sensing to detect random signals corrupted by Gaussian noise. Our analysis is based on a limited time resource assumption. This implies that the time resource ...
