Book Description
L'OBJECTIF DE CETTE THESE EST D'ETUDIER LE PROBLEME DU PARTAGE DE LA RESSOURCE POUR LES RESEAUX GSM DE NOUVELLES GENERATIONS POUR EN TIRER DES ENSEIGNEMENTS ET APPORTER UNE AIDE AU DIMENSIONNEMENT DU SOUS SYSTEME RADIO. LE PROBLEME DU PARTAGE DE LA RESSOURCE, POUR LES RESEAUX GSM OFFRANT DES SERVICES MULTIPLES SUR DES INFRASTRUCTURES HSCSD, GPRS ET EDGE EST AU CENTRE DES TRAVAUX DE THESE. CETTE PROBLEMATIQUE DE LA GESTION ET DU CONTROLE DES FLUX GENERES PAR PLUSIEURS APPLICATIONS EST COMMUNE AUX RESEAUX FIXES. UN NOMBRE CONSIDERABLE D'ETUDES ET DE TRAVAUX DE RECHERCHE ONT MENE A UN LARGE EVENTAIL DE SOLUTIONS, PLUS OU MOINS COMPLEXES ET PLUS OU MOINS PRAGMATIQUES ET REALISABLES, POUR LES RESEAUX A HAUTS DEBITS. CEPENDANT, DANS LE CAS DES RESEAUX MOBILES LA COMPLEXITE EST PLUS GRANDE. L'INFLUENCE DU MILIEU DE PROPAGATION, DE L'ENVIRONNEMENT ET LA PRESENCE DE PLUSIEURS CLASSES DE TERMINAUX AUGMENTENT LA DIFFICULTE. POUR ATTEINDRE LE BUT FIXE, LES TRAVAUX ONT SUIVI UN CHEMINEMENT IDENTIQUE AUX PHASES DE TRANSITION DES RESEAUX EN DEBUTANT PAR UNE ETUDE SUR LE SERVICE HSCSD (SERVICE ORIENTE CIRCUIT A DEBITS SUPERIEURS AU RESEAU GSM ACTUEL). SUITE A UNE ANALYSE GENERALE DU SYSTEME GSM ET DES SPECIFICATIONS ETSI DU SERVICE GPRS, LES TRAVAUX SONT ETENDUS A L'ETUDE DE LA CAPACITE ET DES MECANISMES D'ALLOCATION DE RESSOURCE POUR LE SOUS SYSTEME DE STATION DE BASE DU GPRS.

LES TRAVAUX DE THESE ONT PLUS PARTICULIEREMENT VISE L'ACCES A LA RESSOURCE, L'ALLOCATION DE RESSOURCE ET L'ADAPTATION DE LIEN RADIO POUR AMELIORER LA CAPACITE DES RESEAUX GSM OFFRANT LE SERVICE GPRS.

Book Description
Radio Network Planning and Optimisation for UMTS, Second Edition, is a comprehensive and fully updated introduction to WCDMA radio access technology used in UMTS, featuring new content on key developments. Written by leading experts at Nokia, the first edition quickly established itself as a best-selling and highly respected book on how to dimension, plan and optimise UMTS networks. This valuable text examines current and future radio network management issues and their impact on network performance as well as the relevant capacity and coverage enhancement methods. In addition to coverage of WCDMA radio access technology used in UMTS, and the planning and optimisation of such a system, the service control and management concept in WCDMA and GPRS networks are also introduced. This is an excellent source of information for those considering future cellular networks where Quality of Service (QoS) is of paramount importance. Key features of the Second Edition include: High-Speed Downlink Packet Access (HSDPA) – physical layer, dimensioning and radio resource management Quality of Service (QoS) mechanisms in network for service differentiation Multiple Input – Multiple Output (MIMO) technology Practical network optimisation examples Service optimisation for UMTS and GPRS/EDGE capacity optimisation The ‘hot topic’ of service control and management in WCDMA and GPRS networks, that has evolved since the first edition Companion website includes: Figures Static radio network simulator implemented in MATLAB® This text will have instant appeal to wireless operators and network and terminal manufacturers. It will also be essential reading for undergraduate and postgraduate students, frequency regulation bodies and all those interested in radio network planning and optimisation, particularly RF network systems engineering professionals.

Book Description
Multiple-input, multiple-output (MIMO), which transmits multiple data streams via multiple antenna elements, is one of the most attractive technologies in the wireless communication field. Its extension, called ‘massive MIMO’ or ‘large-scale MIMO’, in which base station has over one hundred of the antenna elements, is now seen as a promising candidate to realize 5G and beyond, as well as 6G mobile communications. It has been the first decade since its fundamental concept emerged. This Special Issue consists of 19 papers and each of them focuses on a popular topic related to massive MIMO systems, e.g. analog/digital hybrid signal processing, antenna fabrication, and machine learning incorporation. These achievements could boost its realization and deepen the academic and industrial knowledge of this field.

Book Description
On the way towards the Information Society, global networks such as the Internet, together with mobile computing, have made wide-area computing over virtual communities a reality. Digital city projects, with the goal of building platforms to support community networking, are going on worldwide. This is the first book devoted to digital cities. It is based on an international symposium held in Kyoto, Japan, in September 1999. The 34 revised full papers presented were carefully selected for inclusion in the book; they reflect the state of the art in this exciting new field of interdisciplinary research and development. The book is divided into parts on design and analysis, digital city experiments, community network experiments, applications, visualization technologies, mobile technologies, and social interaction and communityware.
