Spectrally-Precoded OFDM for 5G Wideband Operation in Fragmented sub-6GHz Spectrum

Autor: Pitaval, Renaud-Alexandre, Popović, Branislav M., Mohamad, Medhat, Nilsson, Rickard, van de Beek, Jaap

We consider spectrally-precoded OFDM waveforms for 5G wideband transmission in sub-6GHz band. In this densely packed spectrum, a low out-of-band (OOB) waveform is a critical 5G component to achieve the promised high spectral efficiency. By precoding

On Extreme Pruning of Random Forest Ensembles for Real-time Predictive Applications

Autor: Fawagreh, Khaled, Gaber, Mohamad Medhat, Elyan, Eyad

Random Forest (RF) is an ensemble supervised machine learning technique that was developed by Breiman over a decade ago. Compared with other ensemble techniques, it has proved its accuracy and superiority. Many researchers, however, believe that ther

Spektral förkodning i OFDM-design och analys

Autor: Mohamad, Medhat

Despite shifting towards mm-wave bands, the sub-6 GHz band will continue to be a fundamental spectral band in 5G. However, the severe congestion in this band makes a well-constrained spectrum a critical requirementof 5G. A well-constrained spectrum m

Backgroud Since EPCs represent a pool of cells which contribute to the endothelial repair after vascular injury, the increased homing and retention of these cells at the site of stent implantation may increase and speed up the process of endotheliali
