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 ...
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 ...
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 ...
Interference cancellation through interference alignment for downlink of cognitive cellular networks
(
Institution of Engineering and Technology
, 2015 , Article)
Interference cancellation through interference alignment (IA) at the downlink of cognitive cellular networks is proposed. IA helps the spatial resources to be shared among primary and secondary cells, and thus it can provide ...
On the statistical distribution of electric field inside jet engines
(2013 , Conference Paper)
Using full wave analysis in 'Ansys HFSS', we obtain the electric field distribution inside a jet engine containing one set of 24 blades due to the excitation provided by a simple Hertzian dipole. Hertzian dipole illuminates ...
Packet relaying control in sensing-based spectrum sharing systems
(2013 , Conference Paper)
Cognitive relaying has been introduced for opportunistic spectrum access systems by which a secondary node forwards primary packets whenever the primary link faces an outage condition. For spectrum sharing systems, cognitive ...
Blind SNR Estimation of Gaussian-Distributed Signals in Nakagami Fading Channels
(
IEEE
, 2015 , Article)
A blind (non-data-aided) SNR estimator using the statistical moments of the received signal is proposed. The proposed envelope-based non-data-aided estimator works for any time-domain Gaussian-distributed signal (e.g. OFDM ...
A simple cross correlation switched beam system (XSBS) for angle of arrival estimation
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
We propose a practical, simple and hardware friendly, yet novel and efficient, angle of arrival (AoA) estimation system. Our intuitive, two-phases cross-correlation-based system requires a switched beam antenna array with ...
