Radio over fiber system based on a hybrid link for next generation of optical fiber communication

International Journal of Electrical and Computer Engineering (IJECE) (2019)

Kaoutar Saidi Alaoui Jaouad Foshi Younes Zouine

<p>Radio over fiber technology will play an important role in solving problems facing wireless technology. Envisaging a global village, people could transmit and receive “anytime, anywhere, and anything”. In addition, the explosive growth in internet applications such as the World Wide Web, demonstrates the tremendous increase in bandwidth and low power that the coming world of multimedia interactive applications will require from future networks. ROF technology uses multicarrier modulation like orthogonal frequency division multiplexing (OFDM), which provides an opportunity of having an increased in bandwidth together with an affordable cost and this idea has recently become a suitable topic for many research works. On the other hand, SAC-OCDMA (Spectral Amplitude Coding Optical Code Division Multiple Access) technique is able to enhance the data rate of system and increase the number of user. In this paper we introduce a ROF link using a hybrid OFDM/SAC-OCDMA technique.</p>

Improvement of parallel interference cancellation technique with hard limiter for DS-OCDMA systems

GLOBECOM '05. IEEE Global Telecommunications Conference, 2005. (2005)

Claire Goursaud Anne Julien‐Vergonjanne Younes Zouine Christelle Aupetit‐Berthelemot J.P. Cances

In direct sequence optical code division multiple access system (DS-OCDMA), one of the principal limitations is due to unipolar coding which introduces multiple access interference (MAI). To mitigate MAI, we have applied a parallel interference cancellation technique (PIC) to remove non-desired users' contribution. We study in this paper, the performances of the PIC improved by hard limiters (HL) placed either before the non-desired users receivers (HL+PIC) or before the desired user receiver (PIC+HL). We develop the HL+PIC and PIC+HL theoretical error probability expression, and show the performances improvement due to such receivers

Deep Learning applied for Spectrum Sensing using multiple and concurrent stages

Research Square (Research Square) (2022)

Hamza Ouamna Zhour Madini Younes Zouine

Abstract Spectrum sensing techniques have many challenges and as one as the most challenges are the noise and interference rejection. Since the occurrence of noise power uncertainty cause the degradation of the performance of the spectrum detector. One of the most techniques of spectrum sensing is the Energy Level detection it could be used with deep learning network to distinguish between presence of signal and noise to this end, we will introduce a comparison between AlexNet, SqueezeNet ResNet101 and LSTM neural networks. To test them in different situations. . ...

Parallel interference cancellation technique applied to DS-OCDMA systems

IEEE/SP 13th Workshop on Statistical Signal Processing, 2005 (2005)

Claire Goursaud Anne Julien‐Vergonjanne Younes Zouine Christelle Aupetit‐Berthelemot J.P. Cances

This paper investigates the parallel interference cancellation (PIC) with hard limiter technique in direct sequence optical code division multiple access system (DS-OCDMA). The PIC technique consists of first estimating the interference by decoding all the non-desired users with a conventional correlation receiver (CCR), and then of removing the estimated interference from the received signal in order to detect the desired user. We study an improvement of this technique: PIC+HL, in which we use an hard limiter (HL) before the CCR of the desired user, in order to limit the interference term due to the non-desired users bad cancellation. We develop the theoretical PIC+HL error probability expression from the PIC one in the chip synchronous case, for optical orthogonal codes (OOC). We demonstrate that such receiver improves significantly the O-CDMA performances regards to conventional receivers

Analysis of realistic DS-OCDMA/VLC for V2X communication using optisystem

2018 4th International Conference on Optimization and Applications (ICOA) (2021)

Anass Kharbouche Zhour Madini Younes Zouine

This paper presents the simulation of the Visible Light Communication (VLC) using Direct Sequence Optical Code Division Multiple Access (DS-OCDMA) system developed with OptiSystem-Matlab Co-simulation. The OCDMA works by assigning to each user a specific code and could provide an asynchronous and simultaneous access to several users. One limitation is the Multiple Access Interference (MAI). The use of very long code sequences is necessary for limiting this effect. Therefore, very large bandwidths are required. An alternative to the speed limitations of electronic devices could be to realize all optical modules. This study consists of demonstrating, by using system simulation, the feasibility of an all-optical Conventional Correlation Receiver dedicated to a DS-OCDMA access network link. We use OPTISYTEM to implement our blocks.

Contribution par la simulation système à l'étude des contraintes des composants optoélectroniques sur la transmission optique utilisant la technique CDMA

Younes Zouine

La technique CDMA (Code Division Multiple Access ou Acces Multiple par Repartition de Codes) est largement utilisee dans le domaine radiofrequence (3G) et suscite un interet croissant pour tirer parti de la largeur de bande offerte par la fibre optique. Associee au DWDM (Dense Wavelength Digital Multplexing), cette technique permettrait en effet un accroissement important du nombre d’utilisateurs au niveau local sans accroitre les besoins en nombre de fibres du reseau de transport. Elle s’accompagnerait donc d’une diminution evidente du cout du bit/km. Ce type d’etude est gouverne par des contraintes liees au traitement du signal et aux performances des composants. Les recherches rapportees dans ce memoire consistent en une etude exploratoire par la simulation systeme des contraintes imposees par les composants et fonctions optoelectroniques qui pourraient repondre aux besoins d’architectures de reseaux locaux optiques bases sur l’application du CDMA. Les limitations dues aux composants des fonctions emission et reception ont ete particulierement etudiees (laser + modulateur, photodiodes, electronique large bande associee,…. ). De plus, les proprietes de la fibre optique (dispersion, attenuation,…. ) sont prises en compte dans le cas specifique des reseaux locaux.
