In this study, we propose a novel interference align- ment technique for the secondary users exploiting the fact that under a power-limitation, a primary user which maximizes its

Then, the impact of the intercell interference on such a scheme is evaluated and the robustness of SS-MC- MA system by mitigating those interferences thanks to frequency

For each library, the percentage of plastome- associated reads was estimated by mapping reads to a reference plastid ge- nome using the Burrows–Wheeler alignment tool (BWA- MEM,

In most cases, coatings produced using these nanostructured materials were compared to those deposited by thermal spraying using conventional (microstructured) powders.. Results

Such considerations aid in determining exactly what information (e.g. metadata, software) should be preserved along with the digital document and in what way. While we cannot
