The magnitude of the problems facing the telecommunication software industry is presently at a point at which software engineers should become deeply involved. This paper presents a research project on advanced telecommunication technology carried out in Europe, called BOOST (Broadband Object-Oriented Service Technology). The project involved cooperative work among telecommunication companies, ...

Toady’s telecommunication network serves as an essential platform in our society for exchange of information in its various possible forms, viz., voice, data and video, and thus helps us in living the life of this modern era. Networking practices have evolved almost over two centuries with an unbelievable range of technologies, services and standards, calling for accommodation of heterogeneous ...

Channel measurement and modeling are important issues when designing ultra wideband (UWB) communication systems. A Precise model of the channel response is inevitable for designing a UWB telecommunication system. In this article signal propagation in indoor environment and LOS condition is evaluated and the appropriate model of this scenario is presented. Parameters such as the power delay prof...

This article describes the current technical level of developments in field continuous-variable quantum key distribution (CV-QKD). Various classifications are described, criteria analyzed, and optimal protocol is selected. The analysis focused around device-dependent schemes with a theoretical emphasis, therefore, detailed device-independent CV-QKD side-channel attacks out scope work. However, ...

Current technological progress is driving Quantum Key Distribution towards a commercial and world widescale expansion. Its capability to deliver unconditionally secure communication will be fundamental feature in the next generations of telecommunication networks. Nevertheless, demonstrations QKD implementation real operating scenario their coexistence with classical telecom infrastructure are ...

This paper considers the process that forms an interchannel transient interference in structure of signal created on basis technology parallel data transmission and frequency distribution with multiplexing phase-modulated – OFDM signal. Based analysis structure, it was determined changes position parameters carrier symbol from composition this create interference. A list can affect appearance v...

multicast routing is one of the most important services in multi radio multi channel (mrmc) wireless mesh networks (wmn). multicast routing performance in wmns could be improved by choosing the best routes and the routes that have minimum interference to reach multicast receivers. in this paper we want to address the multicast routing problem for a given channel assignment in wmns. the channels...

many appealing multicast services such as on-demand tv, teleconference, online games and etc. can benefit from high available bandwidth in multi-radio multi-channel wireless mesh networks. when multiple simultaneous transmissions use a similar channel to transmit data packets, network performance degrades to a large extant. designing a good multicast tree to route data packets could enhance the...
