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, ...

Considering the intrinsic benefits of power line communications, long-lasting lifetime industrial systems and growth IoT, PLC technologies will be part worldwide landscape for many decades. This paper discusses history G3-PLC technology current challenges opportunities identified in real systems. Finally, it introduces recent evolutions within standard, which bring additional performance versat...

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 ...

There is a considerable interest nowadays in making wireless telecommunication more energy-efficient. The sleep-mode mechanism in WiMAX (IEEE 802.16e) is one of such energy saving measures. Recently, Samsung proposed some modifications on the sleep-mode mechanism, scheduled to appear in the forthcoming IEEE 802.16m standard, aimed at minimizing the signaling overhead. In this work, we present a...

With the increasing demand of higher data rate for telecommunication, the IEEE802.11n standard was constituted in 2009. The most important character of the standard is MIMO-OFDM, which not only improves the throughput but also the spectrum efficiency and channel capacity. And in wireless communication, the role of MIMO detectors plays an important part to remove inter-symbol interference (ISI) ...

In this paper we present a tool for the simulation of fluid models of high-speed telecommunication networks. The aim of such a simulator is to evaluate measures which can not be obtained through standard tools in reasonable time or through analytical approaches. We follow an event-driven approach in which events are associated with rate changes in fluid flows. We show that, under some loose res...

Published in Communication of the ACM – Special Issue on Digital Multimedia Systems back in April 1991, “MPEG: A Video Compression Standard for Multimedia Applications” presents an overview of MPEGVideo which has become an international standard for video compression techniques. The development of video technology in the 1980s enabled the use of digital video for telecommunication, digital broa...

given the importance of innovation in a stormy environment with ongoing changes for the organizations, in this study, to identify a noteworthy aspect of community change from the viewpoint of organizational behavior we attempt to examine social capital of employees in an involved organization in change. the aim of this study is to evaluate the impact of social capital components (cognitive, ele...

Speech recognition by machine has not yet been achieved because no suitable specification of the recognition process has been formulated for the machine. The author outlines the disturbances and constraints found in speech, and goes on to a description of the structure implied by the constraints. This description is a prerequisite of speech recognition for two reasons, first to describe general...
