Detection of temporally correlated primary user signal with multiple antennas
(
Springer Verlag
, 2015 , Conference Paper)
In this paper, we address the problem of multiple antenna spectrum sensing in cognitive radios (CRs) when the samples of the primary user (PU) signal as well as samples of noise are assumed to be temporally correlated. We ...
Energy-efficient cooperative relaying protocol for full-duplex cognitive radio users and delay-aware primary users
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper considers a network in which a primary user (PU) may cooperate with a cognitive radio (CR) user for transmission of its data packets. The PU is assumed to be a buffered terminal operating in a time-slotted ...
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 ...
SFET-based multiple antenna spectrum sensing using the second order moments of eigenvalues
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we propose a new detector for multiantenna spectrum sensing in cognitive radios (CR) by exploiting the Separating Function Estimation Test (SFET) framework. Specifically, we consider a blind scenario for ...
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 ...
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 ...
Cooperative access schemes for efficient SWIPT transmissions in cognitive radio networks
(
IEEE
, 2015 , Conference Paper)
We investigate joint information and energy cooperative schemes in a slotted-time cognitive radio network with a primary transmitter-receiver pair and a set of secondary transmitter-receiver pairs. The primary transmitter ...
Time-Frequency Signal Analysis and Processing: A Comprehensive Reference
(
Elsevier Inc.
, 2015 , Book)
Time-Frequency Signal Analysis and Processing (TFSAP) is a collection of theory, techniques and algorithms used for the analysis and processing of non-stationary signals, as found in a wide range of applications including ...
