Condizione: Hervorragend. Zustand: Hervorragend | Produktart: Bücher | Für ein drahtloses Körperbereichsnetzwerk (WBAN) sind mehrere Antennen erforderlich, um verschiedene Arten der Kommunikation an verschiedenen Stellen des Körpers durchzuführen. Um die Anzahl der Antennen zu reduzieren, sind daher Antennen mit flexibler Funktionsweise erforderlich, d. h. eine einzelne Antenne sollte für mehr als eine Art der Kommunikation eingesetzt werden können. Da die WBAN-Antenne am Körper angebracht wird, sollte ihre Form an den Körper angepasst werden können. Die meisten Körperteile sind gekrümmt, sodass eine flache Antenne der Krümmung des Körpers nicht folgen kann und Teile der Antenne hervorstehen, was die natürlichen Körperbewegungen beeinträchtigen kann. Eine gekrümmte Antenne kann der Krümmung des Körpers folgen, daher ist die vorgeschlagene Antenne gekrümmt. Die in diesem Buch beschriebene gekrümmte Antenne ist für die Strahlung bei zwei Frequenzen (2,45 GHz und 5,8 GHz) ausgelegt, und die Modellierung erfolgt mit der CST-Software. Die vorgeschlagene Antenne hat eine geringere Strahlungswirkung auf den Körper. Der SAR-Wert der Antenne beträgt 0,676 W/kg bei 2,45 GHz und 0,294 W/kg bei 5,8 GHz. Diese SAR-Werte liegen deutlich unter den Grenzwerten für SAR in Indien.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The book presents MC-CDMA system for future generation wireless communication system. The analysis is done to evaluate the BER versus SNR ratio in a MC-CDMA wireless system over Rician and Rayleigh fading channels. Finally the system is assessed by using two users whose data is amalgamated as a mixed signal over the AWGN channel and the BER and other parameters are evaluated. The coding schemes used are Walsh Hadamard code, Gold code and STTC code. 96 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -There are number of antennas required for a wireless body area network (WBAN) to perform different types of communications at different positions of body. Therefore to decrease the number of antennas, there is a need of antennas with flexibility of operation that is a single antenna should serves a purpose of more than one type of communication. In case of WBAN antenna is to be placed over body therefore shape of antenna should be adjustable according to the body. Most of the body parts are curved therefore flat antenna cannot follow the curvature of body and some of the part of antenna will be protruding, which can interfere the natural body movements. The curved shape antenna can follow the curvature of body therefore proposed antenna is made curved. The curved antenna discussed in this book is designed to be radiating at two frequencies 2.45 GHz and 5.8 GHz and modeling is done using CST software. The proposed antenna has less effect of radiations on body. The SAR value of antenna is 0.676 W/kg at 2.45 GHz and 0.294 W/kg at 5.8 GHz. These values of SAR are well below the limits for SAR in India. 104 pp. Englisch. …

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Se necesitan varias antenas para que una red inalámbrica de área corporal (WBAN) pueda realizar diferentes tipos de comunicaciones en diferentes posiciones del cuerpo. Por lo tanto, para reducir el número de antenas, se necesitan antenas con flexibilidad de funcionamiento, es decir, una sola antena debe servir para más de un tipo de comunicación. En el caso de las antenas WBAN, que se colocan sobre el cuerpo, la forma de la antena debe ser ajustable según el cuerpo. La mayoría de las partes del cuerpo son curvas, por lo que una antena plana no puede seguir la curvatura del cuerpo y algunas partes de la antena sobresaldrán, lo que puede interferir en los movimientos naturales del cuerpo. La antena de forma curva puede seguir la curvatura del cuerpo, por lo que la antena propuesta es curva. La antena curvada que se describe en este libro está diseñada para irradiar en dos frecuencias, 2,45 GHz y 5,8 GHz, y el modelado se realiza con el software CST. La antena propuesta tiene menos efecto de radiación sobre el cuerpo. El valor SAR de la antena es de 0,676 W/kg a 2,45 GHz y de 0,294 W/kg a 5,8 GHz. Estos valores de SAR están muy por debajo de los límites establecidos para el SAR en la India.…
