On the Performance of Hadamard Ratio Detector-Based Spectrum Sensing for Cognitive Radios
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
We consider the problem of multiantenna spectrum sensing (SS) in cognitive radios (CRs) when the receivers are assumed to be uncalibrated across the antennas. The performance of the Hadamard Ratio Detector (HRD) is analyzed ...
Securing cognitive radio networks against primary user emulation attacks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
CR is a promising technology for next-generation wireless networks in order to efficiently utilize the limited spectrum resources and satisfy the rapidly increasing demand for wireless applications and services. Security ...
Energy-efficient cooperative cognitive relaying schemes for cognitive radio networks
(
Elsevier B.V.
, 2018 , Article)
We investigate a cognitive radio network in which a primary user (PU) may cooperate with a cognitive radio user (i.e., a secondary user (SU)) for transmissions of its data packets. The PU is assumed to be a buffered node ...
