FSO-CDMA Systems Supporting end-to-end Network Slicing

Thiago Raddo, Javier Perez-Santacruz, Ulf Johannsen, Iyad Dayoub, Shyqyri Haxha, Idelfonso Tafur Monroy, Antonio Jurado-Navas

A new flexible, secure FSO-CDMA system supporting end-to-end network resource slicing is proposed and investigated. New mathematical formalisms considering distinct turbulence conditions are derived. The system supports different applications, use cases, and traffic requirements.

Performance assessment of dual-polarized 5G waveforms and beyond in directly modulated DFB-laser using Volterra equalizer

Oussama Gharbi, Sofien Mhatli, Iyad Dayoub, Shyqyri Haxha, Rabah Attia, Adel Aldalbahi, Adrian Jaesim

We investigate the performance of 25-Gbps dual-polarized orthogonal frequency division multiplexing (OFDM)-based modulation in a directly modulated distributed feedback (DFB)-laser over 25 km of single-mode fiber. A Volterra equalizer is used to compensate for the nonlinear effects of the optical…

Channel Estimation Techniques for Millimeter-Wave Communication Systems: Achievements and Challenges

Kais Hassan, Mohammad Masarra, Marie Zwingelstein, Iyad Dayoub

The fifth-generation (5G) of cellular networks and beyond requires massive connectivity, high data rates, and low latency. Millimeter-wave (mmWave) communications is a key 5G enabling technology to meet these requirements thanks to its technical potentials that can be integrated with other 5G…

Performance analysis of UFMC waveform in graded index fiber for 5G communications and beyond

Mahdi Kasmi, Sofien Mhatli, Faouzi Bahloul, Iyad Dayoub, Kyunghwan Oh

For the first time, we demonstrate in this paper an intensity-modulation direct-detection (IMDD) universal filtered multi-carrier (UFMC) system through several hundred meters of multimode fiber (MMF) that can be adopted for 5G communications and beyond. The proposed system is simulated and…

Performance of ZCZ codes in QS-DS-CDMA communication systems

Mouad Addad, Ali Djebbari, Iyad Dayoub

Zero correlation zone (ZCZ) codes have been recently adopted for many communication systems based on code division multiple access (CDMA). In this paper, we focus on the use of ZCZ codes in quasi-synchronous direct-sequence (QS-DS) CDMA. To ensure Interference-free communication, spreading ZCZ…

Joint Interference Cancellation for Multi-Carrier Modulation-Based Non-Orthogonal Multiple Access

Michel Saideh, Yamen Alsaba, Iyad Dayoub, Marion Berbineau

This letter considers the implementation of Non-Orthogonal Multiple Access (NOMA) scheme with different waveforms. The performance of the adopted Multi-Carrier Modulations (MCM)-based NOMA system is evaluated in doubly selective channel scenario. In addition, the imperfect Successive Interference…

Extensive Capacity Simulations of Massive MIMO Channels for 5G Mobile Communication System

Mahdi Kasmi, Sofien Mhatli, Iyad Dayoub

In this work, an analytic extension of massive MIMO capacity for 5G mobile communication systems is firstly developed. Then, the capacity limit and multiplexing gain are investigated in simulations for different massive MIMO configurations. Furthermore, the two calculated metrics are performed as a…
