Abstract:

This thesis addresses the phenomena of Mobile Virtual Network Operators (MVNO): often MVNO do not come from the telecom sector but they rent the network to mobile operators to become fully mobile operators on their own. So they compete directly not only with the other mobile operators but also with their hosting mobile operator.<p><p>Hosting MVNOs, supporting them from both operational and commercial perspectives are new challenges for the mobile operators: they have to set up a specific internal organization because they used to be a vertically integrated industrial structure.

This study aimed to investigate the RNA expression profile (12,000 genes) and HSP family protein expression levels after either acute 1-hour or chronic 4-day intermittent exposures to simulated GSM radiation in a human primary fibroblast model.

Abstract:

A wireless communication system allows two parties to exchange information over long distances. The antenna is the component of a wireless communication system that allows information to be converted into electromagnetic radiation that propagates through the air. A system using an antenna with a highly directional beam pattern allows for high power transmission and reception of data. For a directional antenna to serve its purpose, it must be accurately pointed at the object it is communicating with. To communicate with a mobile node, knowledge of the mobile node's position must be gained so th

Abstract:

In recent years, mobile communication networks have experienced significant evolution. The 3G mobile communication system, UMTS, employs WCDMA as the air interface standard, which leads to quite different mobile network planning and dimensioning processes compared with 2G systems. The UMTS system capacity is limited by the received interference at NodeBs due to the unique features of WCDMA, which is denoted as `soft capacity'. Consequently, the key challenge in UMTS radio network planning has been shifted from channel allocation in the channelized 2G systems to blocking and outage probabilitie

Abstract:

The objective of the thesis is concerned on the problem of detecting superpositional signals in a wireless channel. In many wireless systems, an observed signal is commonly represented as a linear combination of the transmitted signal with the interfering signals dispersed in space and time. These systems are generally known as the interference-limited systems. The mathematical model of these systems is generally referred as a superpositional model. A distinguished characteristic of signal transmission in a time-varying wireless channel is that the channel process is not known a priori. Reliab

碩士<br>元智大學<br>電機與資訊工程研究所<br>87<br>In this thesis, we consider using smart antenna array technique to combat Channel fading, multipath and Co-Channel Interference(CCI) in GSM/DCS-1800 mobile communication system,thereby increasing both performance and capacity .In contrast with the conventional nonlinear GMSK signal for GSM, we approximate the GMSK signal in terms of a first-order linear AMP(Amplitude Modulation Pulse) model. Then we exploit de-rotation skill and fractionally spaced structure to construct an SIMO linearized GMSK model, and develop various multichannel or filter Bank receiver st

碩士<br>國立成功大學<br>航空太空工程學系<br>89<br>This thesis presents the design and implementation of an Automatic Dependent Surveillance system using Global System for Mobile communication (ADS-GSM). By using the ADS-GSM, the Surveillance Center can get the Users’ position data via the communication subsystem of ADS-GSM, and can display the positioning data in the geodetic information system (GIS) to enhance the surveillance capability and reduce complexity. Now the General Packet Radio Service (GPRS), a new GSM service, has been proposed to improve the GSM communication in data link capability as well a

M.Com. (Informatics)<br>This research has the aim of creating a low-cost, contactless, micro-payment framework to support micro-payments for the informal taxi industry in South Africa. The informal taxi industry is a prime example of an industry that needs simple and effective payments for low-cost services where the primary medium of payment is currently cash. Challenges of currently used are the security of cash, the difficulty for the taxi driver to collect cash, and the auditability of cash from the perspective of the taxi owner. Furthermore, the taxi owner does not know the routes the tax

M.Ing.<br>The increase of interest in the development of radio communications, both terrestrial and satellite is reaching far and beyond the most optimistic expectations. There has been an accelerated emergence of newer technologies, all claiming highly coveted radio frequency spectrum resources. With the push for the development of location based services, utilizing satellite com- communications for military purposes and later for civilian use; there has been a parallel development in terrestrial communications technology making it possible to implement cost efficient reliable user systems fo
