Cette thèse étudie les technologies porteuses de la 5ème génération de communication mobile telle que le MIMO et Massive MIMO ainsi que les divers challenges amenés par l’apparition de ces nouvelles technologies. Dans ce but un banc de mesure spécifique pour la caractérisation des performances des antennes MIMO en WLAN et LTE a été mis en œuvre. Dans un premier temps le banc de mesure a été réalisé à partir d’instruments de mesures Rhodes & Schwarz ; L’opportunité de travailler avec EURECOM nous a amenés à développer un second banc de test en utilisant l’OpenAirInterface, une plateforme op

Ces nouvelles contraintes d’encombrement et de performances auxquelles doivent répondre les émetteurs-récepteurs ont un impact direct sur les spécifications techniques des amplificateurs de puissance (PA).

Abstract:

Nowadays, the rapid growth of mobile communications is changing the world towards a fully connected society. Current 4G networks account for almost half of total mobile traffic, and in the forthcoming years, the overall mobile data traffic is expected to dramatically increase. To manage this increase in data traffic, operators adopt network topologies such as Heterogeneous Networks. Thus, operators can de ploy hundreds of small cells for each macro cell, allowing them to reduce coverage hales and/or lack of capacity. The advent of this technology is expected to tremendously increase the numbe

Abstract:

The increasing demand for connectivity and broadband wireless access is leading to the fifth generation (5G) of cellular networks. The overall scope of 5G is greater in client width and diversity than in previous generations, requiring substantial changes to network topologies and air interfaces. This divergence from existing network designs is prompting a massive growth in research, with the U.S. government alone investing $400 million in advanced wireless technologies. 5G is projected to enable the connectivity of 20 billion devices by 2020, and dominate such areas as vehicular networking an

Abstract:

As mobile networks continue to evolve, two major problems have always existed that greatly affect the quality of service that users experience. These problems are (1) efficient resource management for users at the edge of the network and those in a network coverage hole. (2) network coverage such that improves the quality of service for users while keeping the cost of deployment very low. In this study, two novel algorithms (Collaborative Resource Allocation Algorithm and Memetic-Bee-Swarm Site Location-Allocation Algorithm) are proposed to solve these problems.

One of the challenges of the mobile industry is to cope with the growth of mobile traffic demand expected for the next years, primarily driven by the increasing usage of mobile video services.

In the thesis, the user body effect on antennas in a mobile terminal is discussed. In order to overcome the degradation of Multiple-Input Multiple-Output (MIMO) performance due to the user body effect, a quad-elements MIMO antenna array which can mitigate the body effect through an adaptive antenna switching method is introduced for 4G mobile terminals. In addition, various bezel MIMO antennas that are robust to the impedance mismatching caused by the user effect have also been presented. The study of user body effect is later extended to frequency bands at 15 GHz and 28 GHz for future 5G comm

In this work the 5G core network architecture has been explored: starting from the enabling technologies that are supporting the "revolution" and looking in depth at the current 4G LTE network architecture, we tried to find a solution to bridge the gap between these two totally different architecture. Once the solution has been found, we used a simulation platform provided by the ONF (Open Networking Foundation) that demonstrates the feasibility of such approach.

Femtocells are seen to be the future of Long Term Evaluation (LTE) networks to improve the performance of indoor, outdoor and cell edge User Equipments (UEs).

It is said that 30% of total served UEs in LTE networks are vehicular, which poses challenges in LTE networks due to their high mobility, high vehicular penetration loss (VPL), high path loss and high interference. Therefore, self-optimising and dynamic solutions are required to incorporate more intelligence into

The non-deterministicness can lead to message race faults, where the order of messages can result in false truths.

Abstract:

At present, the current 4G systems provide a universal platform for broadband mobile services; however, mobile traffic is still growing at an unprecedented rate and the need for more sophisticated broadband services is pushing the limits on current standards to provide even tighter integration between wireless technologies and higher speeds. This has led to the need for a new generation of mobile communications: the so-called 5G. Although 5G systems are not expected to penetrate the market until 2020, the evolution towards 5G is widely accepted to be the logical convergence of internet service

Abstract:

The Industrial Internet of Things (IIoT) is one of the key technologies of Industry 4.0 thatwill be an integral part of future smart and sustainable production. The current constitutedmodels for estimating Quality of Experience (QoE) are mainly targeting the multimediasystems. Present models for evaluating QoE, specifically leveraged by the expensivesubjective tests, are not applicable for IIoT applications. This work triggers the discussionon defining the QoE domain for IIoT services and applications. Industry-specific KPIs areproposed to assure QoE by linking business and technology domains.

Abstract:

Depuis près d'un demi-siècle, l'industrie de la microélectronique a prospéré grâce à la miniaturisation des transistors Si CMOS. Cependant, la course à la miniaturisation se heurtera dans les prochaines années à des barrières physiques incontournables. Ainsi, de nombreux travaux technologiques sont en cours de réalisation sur les technologies émergentes et avancées. Ces technologies, notamment le graphène et la CMOS FD-SOI, représentent de grandes opportunités dans le domaine de la microélectronique, et notamment pour la conception de circuits radiofréquences et millimétriques. En outre, avec

Abstract:

[EN] In today's information society, there is a growing need to access data communication services ubiquitously, with mobility and increasingly higher data rates. This society's demand has motivated the development of the fourth generation of mobile communications (4G) and its evolution towards the fifth generation (5G). This development has required a revolution on the radio interface of the mobile communications systems, and, consequently, has significantly modified their capabilities and their radio resource management. This is the case of the technology known as Long Term Evolution (LTE) a

A partir de la cinquième génération, les réseaux mobiles devront supporter une croissance exponentielle du nombre d'appareils connectés de différents types, ceci étant l'un des piliers d'une stratégie globale de numérisation accélérée. En plus de cette croissance de connectivité, ces réseaux devront également supporter et offrir divers services pour de nouvelles industries aux exigences hétérogènes. Les concepteurs et développeurs de réseaux 5G sont alors contraints de fournir de nouvelles solutions et d'optimiser celles qui existent pour contenir les demandes croissantes de bande passante et
