Taschenbuch. Zustand: Neu. Neuware -The growth of mobile communication over last few years has become extraordinary and unbelievable. The increased market of mobile users and their will to connect everywhere at any time to access high data rate services with different hardware makes the mobile communication extraordinary. 3G based WCDMA systems provide a platform to access all these services with support of latest handsets to large number of users. But random channel impairments, co-channel & MAI degrades the WCDMA performance and becomes a major obstacle for users. So,there is a need to analyze the WCDMA performance over various fading channels. In this book, performance is analyzed with the help of gaussian approximation technique under various fading distributions and different power control mechanism with receiver structures. Different kind of fading like weibull, rayleigh, rician & nakagami have been applied to Gaussian Approximated WCDMA system to generate faded transmitted signal and BER is calculated accordingly at the output of conventional receiver. Performance comparison b/w perfect power control based rake receiver and conventional receiver is also done under the severer effect of rayleigh fading.Books on Demand GmbH, Überseering 33, 22297 Hamburg 76 pp. Englisch.

El aumento del mercado de usuarios de móviles y su deseo de conectarse en cualquier momento y lugar para acceder a servicios de alta velocidad de datos con distintos equipos hace que la comunicación móvil sea extraordinaria. Los sistemas WCDMA basados en 3G ofrecen a un gran número de usuarios una plataforma para acceder a todos estos servicios con los terminales más modernos. Pero las deficiencias aleatorias del canal, el co-canal y el MAI degradan el rendimiento de WCDMA y se convierten en un obstáculo importante para los usuarios. Por lo tanto, es necesario analizar el rendimiento de WCDMA en varios canales de desvanecimiento. En este libro, el rendimiento se analiza con la ayuda de la técnica de aproximación gaussiana bajo varias distribuciones de desvanecimiento y diferentes mecanismos de control de potencia con estructuras de receptor. Se han aplicado diferentes tipos de desvanecimiento como weibull, rayleigh, rician & nakagami al sistema WCDMA de aproximación gaussiana para generar una señal transmitida desvanecida y la BER se calcula en consecuencia a la salida del receptor convencional. También se comparan las prestaciones del receptor basado en control de potencia perfecto con las del receptor convencional bajo el efecto más severo del desvanecimiento rayleigh.Books on Demand GmbH, Überseering 33, 22297 Hamburg 60 pp. Spanisch.

Taschenbuch. Zustand: Neu. Neuware -La croissance des communications mobiles au cours des dernières années est devenue extraordinaire et incroyable. L'augmentation du nombre d'utilisateurs de téléphones mobiles et leur volonté de se connecter partout et à tout moment pour accéder à des services à haut débit avec différents matériels rendent la communication mobile extraordinaire. Les systèmes WCDMA basés sur la technologie 3G fournissent une plateforme permettant à un grand nombre d'utilisateurs d'accéder à tous ces services à l'aide des combinés les plus récents. Cependant, les dégradations aléatoires des canaux, l'humidité dans le même canal, la MAI dégradent les performances du WCDMA et deviennent un obstacle majeur pour les utilisateurs. Il est donc nécessaire d'analyser les performances du WCDMA sur différents canaux d'évanouissement. Dans ce livre, les performances sont analysées à l'aide de la technique d'approximation gaussienne sous différentes distributions d'évanouissement et différents mécanismes de contrôle de la puissance avec des structures de réception. Différents types d'évanouissement tels que weibull, rayleigh, rician & ; nakagami ont été appliqués au système WCDMA à approximation gaussienne pour générer un signal transmis affaibli et le TEB est calculé en conséquence à la sortie d'un récepteur conventionnel.Books on Demand GmbH, Überseering 33, 22297 Hamburg 60 pp. Französisch.

Taschenbuch. Zustand: Neu. Neuware -La crescita della comunicazione mobile negli ultimi anni è diventata straordinaria e incredibile. L'aumento del mercato degli utenti di telefonia mobile e la loro volontà di connettersi ovunque e in qualsiasi momento per accedere a servizi ad alta velocità di trasmissione dati con hardware diversi rendono la comunicazione mobile straordinaria. I sistemi WCDMA basati su 3G forniscono una piattaforma per accedere a tutti questi servizi con il supporto di telefoni di ultima generazione a un gran numero di utenti. Tuttavia, i disturbi casuali del canale, il co-channel & e il MAI degradano le prestazioni del WCDMA e diventano un ostacolo importante per gli utenti. È quindi necessario analizzare le prestazioni del WCDMA su vari canali in fading. In questo libro, le prestazioni vengono analizzate con l'aiuto della tecnica di approssimazione gaussiana in presenza di varie distribuzioni di fading e di diversi meccanismi di controllo della potenza con strutture di ricezione. Diversi tipi di fading come weibull, rayleigh, rician e nakagami sono stati applicati al sistema WCDMA con approssimazione gaussiana per generare un segnale trasmesso sbiadito e il BER viene calcolato di conseguenza all'uscita del ricevitore convenzionale. Il confronto delle prestazioni tra il ricevitore rake basato su un perfetto controllo di potenza e il ricevitore convenzionale viene effettuato anche sotto l'effetto più severo del rayleigh fading.Books on Demand GmbH, Überseering 33, 22297 Hamburg 60 pp. Italienisch.

Taschenbuch. Zustand: Neu. Neuware -Das Wachstum der mobilen Kommunikation in den letzten Jahren ist außergewöhnlich und unglaublich geworden. Der wachsende Markt an Mobilfunknutzern und ihr Wunsch, sich überall und jederzeit zu verbinden, um mit unterschiedlicher Hardware auf Dienste mit hoher Datenrate zuzugreifen, machen die mobile Kommunikation außergewöhnlich. 3G-basierte WCDMA-Systeme bieten eine Plattform für den Zugang zu all diesen Diensten mit Unterstützung der neuesten Handsets für eine große Anzahl von Benutzern. Aber zufällige Kanalbeeinträchtigungen, Co-Channel & MAI verschlechtert die WCDMA-Leistung und wird zu einem großen Hindernis für die Benutzer. Es besteht also die Notwendigkeit, die WCDMA-Leistung bei verschiedenen Fading-Kanälen zu analysieren. In diesem Buch wird die Leistung mit Hilfe der Gauß'schen Approximationstechnik unter verschiedenen Fading-Verteilungen und verschiedenen Leistungssteuerungsmechanismen mit Empfängerstrukturen analysiert. Verschiedene Arten von Fading wie Weibull, Ryleigh, Rician & Nakagami wurden auf ein Gauß-approximiertes WCDMA-System angewendet, um ein verblasstes Sendesignal zu erzeugen, und die BER wird entsprechend am Ausgang eines konventionellen Empfängers berechnet. Ein Leistungsvergleich zwischen einem auf perfekter Leistungssteuerung basierenden Rake-Empfänger und einem konventionellen Empfänger wird auch unter dem schwereren Effekt des Ryleigh-Fadings durchgeführt.Books on Demand GmbH, Überseering 33, 22297 Hamburg 60 pp. Deutsch.
