Fractional low order cyclostationary-based spectrum sensing in cognitive radio networks
(
Springer Verlag
, 2015 , Conference Paper)
In this paper, we study the problem of cyclostationary spectrum sensing in cognitive radio networks based on cyclic properties of linear modulations. For this purpose, we use fractional order of observations in cyclic ...
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 ...
Distributed power control for carrier aggregation in cognitive heterogeneous 5G cellular networks
(
Springer Verlag
, 2015 , Conference Paper)
In this paper, we study the distributed optimal power allocation for the carrier aggregation in next generation (5G) cognitive radio networks. The presented study relies on the power control and carrier aggregation principles ...
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 ...
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 ...
Multiuser scheduling on downlink communications by using adaptive hierarchical modulation
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we propose a novel downlink system that is able to maximize the number of users which could be served with high correct decoding probability while, minimizing the total consumed energy for data reconstruction ...
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 ...
On the Design of a Relay-Assisted Network
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
A relay network composed of a source, a set of relays, and a destination is considered. A queueing framework is proposed, in which each node maintains a buffer to store its incoming traffic. An optimization-based formulation ...
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 ...
