Mobile positioning using wireless telecommunication networks has been the focus of recent research as a potential, cost-effective solution for positioning a mobile user in urban environment, where the performances of Global Navigation Satellite System (e.g. availability, dilution of precision) may be reduced, while the availability of wireless telecommunication networks is important. Such resea...

Einstein-Podolsky-Rosen (EPR)-entangled state light field at a telecommunication wavelength of 1.5 μm is an important quantum source for realizing the continuous variable information processing and some protocols over optical fiber channel. When EPR-entangled distributed channel, disentanglement always present because EPR entangled interacts with It affects performance processing. In this paper...

A very significant evolution of mobile telecommunication technologies is the introduction of the high-speed downlink shared channel used by many users to efficiently accommodate packets in networks. In a wireless environment, because of the time-varying channel fluctuations of wireless links, efficient use of the large available bandwidth cannot be achieved without adopting sophisticated channe...

The services and communication facilities around the world are continuously increasing. This process of expansion of telecommunications infrastructure has enabled a new set of applications and systems that was previously impractical. Some of these systems, such as the standard ISDB-T (Integrated Services Digital Broadcasting Terrestrial) on which the Brazilian System of Digital TV (SBTVD) is ba...

The intelligent transportation systems (ITS) framework from European Telecommunication Standards Institute (ETSI) imposes requirements on the exchange of periodic safety messages between components of ITS such as vehicles. In particular, it requires ETSI standardized Decentralized Congestion Control (DCC) algorithm to regulate the beaconing activity of vehicles based on wireless channel utiliza...

At WRC-07, the frequency band 3500 MHz has been allotted for the next generation of mobile International Mobile Telecommunication-Advanced (IMT-Advanced). Meanwhile this band is already in used by fixed services, which means that harmful interference probability may be transpired. In this paper, the coexistence between the two services in various geographical deployment areas (dense urban, urba...

The exceptional growth of the telecommunication industry in recent years fueled by the widespread popularity of mobile phones and wireless computer networking. The demand of wireless communication is constantly growing and need the tether less connectivity. The major limitations to this growth is the disadvantages of traditional wireless communication System due to the limitations of available ...

In this paper, multi-cell channel estimation algorithm based on successive interference cancellation (SIC).This channel algorithm is also used for Time Division Synchronization Code Division Multiple Access Systems (TD-SCDMA). TD-SCDMA is the country's standard of 3G mobile telecommunication. This reduces the number of users in each timeslot, which reduces the implementation complexity of multi...
