Cognitive Radio Networks with Probabilistic Relaying: Stable Throughput and Delay Tradeoffs
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
This paper studies fundamental throughput and delay tradeoffs in cognitive radio systems with cooperative secondary users. We focus on randomized cooperative policies, whereby the secondary user (SU) serves either its own ...
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 ...
