Adaptive modulation in multi-user cognitive radio networks over fading channels
(
IEEE Computer Society
, 2013 , Conference Paper)
In this paper, the performance of adaptive modulation in multi-user cognitive radio networks over fading channels is analyzed. Multi-user diversity is considered for opportunistic user selection among multiple secondary ...
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 ...
Connectivity Analysis of THz-based UAV-BS Considering Mobile Users
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Conference Paper)
With the growth of the high data rate demands and the continuous increase in the connected devices and user's equipment, the spectrum resources will not be sufficient. Terahertz (THz) spectrum band provides wide bandwidth ...
A Study of Multihop mmW Aerial Backhaul Links
(
Institute of Electrical and Electronics Engineers Inc.
, 2022 , Conference Paper)
The main contribution of this paper is to analyze a long networked flying platform (NFP)-based millimeter wave (mmWave) backhaul link that is offered as a cost effective and easy to deploy solution to connect a disaster ...
Detecting Attackers during Quantum Key Distribution in IoT Networks using Neural Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Conference Paper)
Internet of Things (IoT) deployments face significant security challenges due to the limited energy and computational power of IoT devices. These challenges are more serious in the quantum communications era, where certain ...
A degrees of freedom-optimal scheme for SISO X channel with synergistic alternating CSIT
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
In this paper, the degrees of freedom (DoF) of the two-user single input single output (SISO) X channel are investigated. Three cases are considered for the availability of channel state information at the transmitters ...
Finite-sample size multiple antennas spectrum sensing
(2012 , Conference Paper)
In this paper, we consider the problem of multiple antenna spectrum sensing in Cognitive Radios (CR) by exploiting the prior information about unknown parameters. Specifically, we consider a blind spectrum sensing problem ...
Band allocation for cognitive radios with buffered primary and secondary users
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, we study band allocation of Ms buffered secondary users (SUs) to Mp orthogonal primary licensed bands, where each primary band is assigned to one primary user (PU). Each SU is assigned to one of the available ...
Compressed wideband spectrum sensing with correlated subband occupancy in multi-antenna cognitive radios
(2012 , Conference Paper)
In this paper, we investigate the use of multiple antennas at the cognitive radio receiver for improved wideband spectrum sensing and exploit compressed sensing to reduce the extremely high sampling rate of wideband signal. ...
Conformal circular patch antenna array design for use in jet engines
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
A novel low profile two elements array of circular patch antenna is designed, analyzed and simulated for wireless sensor applications in extremly harsh environments like jet engines. The designed antenna is simulated using ...
