(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
Drones or unmanned aerial vehicles are having an increased popularity in all fields of applications such as transportation, traffic monitoring, military surveillance etc. However, this technology can be used for destruction ...
Secure Communications Using Directional Modulation
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Limitations on the wireless communication resources (i.e., time and frequency) introduces the need for another domain that can help communication systems to match the increasing demand on high data transfer rates and quality ...
Flying Social Networks: Architecture, Challenges and Open Issues
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
This article presents a flying social network (FSN), which is a kind of flying ad hoc network (FANET) that implies human attributes and relationships. By the accurate analyzed social relationship of unmanned aerial vehicle ...
Applying statistical antenna approach in jet engine electromagnetic field analysis
(2013 , Conference Paper)
In this paper, statistical antenna approach is applied to develop an equivalent model for the fields generated by a fixed excitation inside a jet engine with dynamic rotating blade. The equivalent model is represented by ...
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 ...
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. ...
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 ...
On the study of field uniformity inside jet engines
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, the field uniformity of axial electric field component inside an anisotropic jet engine environment is analyzed by using Ansys HFSS simulation tool. The standard deviation based approach is used for the ...
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 ...
The effect of additional statistical side information on multiple antenna spectrum sensing
(2012 , Conference Paper)
In this paper, we consider the problem of multiple antenna spectrum sensing in Cognitive Radios (CR) when some or all parameters are unknown. The Generalized Likelihood Ratio (GLR) test is the convectional method to solve ...
