Mobile Ad-hoc Network is a self configurable routing protocol. Nodes in MANET can shift freely from one place to another place and each node in MANET can take action as a transmitter, receiver and router. WiMAX is a telecommunication technology standard which provides fixed and mobile Internet access. Access Server Network (ASN) in WiMAX provides the layer 2 connectivity to the user equipments....

1 SDL is the premier language for specification, design and development of real time systems, and in particular for telecommunication applications. SDL-2000 became the international standard in force in November 1999, replacing the previous version. This paper gives an overview of SDL-2000 and fills the gap between previously published tutorials and the current SDL standard.

Telecommunications are strategic assets for the design and operation of train control systems based on automatic train protection to prevent errors due to the human factor. The ERTMS/ETCS train control system developed in Europe is considered a world-wide de facto standard. It utilizes a dedicated telecommunication network based on the GSM-R system. This approach is not economically sustainable...

The evolving liberalisation of the European telecommunication markets will result in a growing competition among service and network providers. In such an environment the rapid development and deployment of new telecommunication services take on increasing significance. The use of distributed object-oriented platforms that provide a set of common and generic building blocks for applications hel...

This paper presents the electromagnetic interference and electromagnetic susceptibility characteristics of the railway telecommunication intra-subsystem. These are for assessing the electromagnetic compatibility inside the railway telecommunication subsystem and providing input data for electromagnetic compatibility analysis of other subsystems (intra-system analysis). This paper shows the opti...

This paper introduces the Telecommunication Outside Plant Markup Language (TOPML), an OpenGis GML (Geographic Markup Language) application schema designed to describe telecommunication outside plant data in which geographical information is an important issue. TOPML uses the standard OpenGis GML schema to include geographic properties to georeferenced telecom network elements. The use of TOPML ...

Sure, most of you are aware that right now everyone is thinking or at least the industry and researchers about next generation, first generation what will 5G be, a significant part telecommunication standard has been finalised, in particular error control codes be used telecommunication. One called Low-Density Parity Check code (or LDPC for short), other Polar Code. These two famous celebrated ...

A soft decoding technique is discussed in this paper to improve the performance of long-distance optical networks (LDOTNs). LDOTNs are affected by phase noise and nonlinearities generated inside fiber. The investigations proposed LDOTN were carried out dual-polarization 16-quadrature amplitude modulation (DP-16QAM), DP-64QAM over single-mode fiber (SMF) digital signal processing (DSP) methodolo...
