Enhanced Pilot-Based Spectrum Sensing Algorithm
Ghaith Hattab, Mohamed Ibnkahla
In this paper, we develop an enhanced pilot-based spectrum sensing algorithm for cognitive radio. Unlike conventional pilot-based detectors which merely detect the presence of pilo…
Multiband Spectrum Access: Great Promises for Future Cognitive Radio Networks
Ghaith Hattab, Mohammed Ibnkahla
Cognitive radio has been widely considered as one of the prominent solutions to tackle the spectrum scarcity. While the majority of existing research has focused on single-band cog…
Joint Design of Optimal Cooperative Jamming and Power Allocation for Linear Precoding
Jun Yang, Il-Min Kim, Dong In Kim
Linear precoding and cooperative jamming for multiuser broadcast channel is studied to enhance the physical layer security. We consider the system where multiple independent data s…
Investigating the origin of cyclical wind variability in hot, massive stars - I. On the dipolar magnetic field hypothesis
A. David-Uraz, G. A. Wade, V. Petit +9
OB stars exhibit various types of spectral variability associated with wind structures, including the apparently ubiquitous discrete absorption components (DACs). These are propose…
Spatial ordering of nano-dislocation loops in ion-irradiated materials
S. L. Dudarev, K. Arakawa, X. Yi +4
Defect microstructures formed in ion-irradiated metals, for example iron or tungsten, often exhibit patterns of spatially ordered nano-scale dislocation loops. We show that such or…
On the Convergence of the Mean Shift Algorithm in the One-Dimensional Space
Youness Aliyari Ghassabeh
The mean shift algorithm is a non-parametric and iterative technique that has been used for finding modes of an estimated probability density function. It has been successfully emp…
