Modern telecommunications networks are designed in such a way that to accommodate a mix of heterogeneous wireless networks of traffic classes to perform different services. Traffic models are important to analyze the performances of telecommunication systems namely traffic, interference and channel estimation. This paper provides an approach for evaluating the channel availability and predictin...

Although modern telecommunication has drastically our daily lives, the audibly challenged cannot benefit from such telecommunication because it is based on phonetic media. This paper introduces a new telecommunication system for sign language utilizing VR technology, which enables natural sign conversation on the conventional analogue telephone line. In this method, a person converses with his/...

A new CMOS PCM channel fiiter is described, which includes transmit and receive filters on a single die. This chip displays an idle-channel noise of typically O dBrnCO, a POWeIsupply rejection ratio of 40-50 dB at 1 kHz, and a fully operational power dissipation of only 35 mW, making it very cost effective in telecommunication switching systems. The design of this chip, including architectural,...

In this paper, by using MATLAB/Simullink software, Xilinx System Generator, Xilinx Alliance tools, Xilinx XSE & ISE and Modelsim XE software, a real-time transceiver platform is built up to analyze and verify the effectiveness and usability of the implemented FPGA-based DAB (Digital Audio Broadcasting) channel decoder. This hardware-level testing platform is completely conforming to DAB specifi...

In modern computer transmission networks the information is transferred by non-cable and cable communication channels, the latter are divided into three fundamental classes: cables on the basis of twisted pairs, coaxial cables and fiber optic communication channels. The fiber optic channels are unidirectional, therefore the full connectivity of a network can be achieved with the help of double ...

the aim of this research is to prioritize the key factors for implementation of idea virtual bank (ivb) in telecommunication industry. the current applied and descriptive research was conducted based on a survey. the population of this research consisted of all users of ivb and idea submitters to suggestion system of telecommunication industry in province of razavi-khorasan that 70 of them were...

In this work, we establish some efficient and practical design rules for the implementation of single-channel ultra-high speed (>160-Gbit/s) telecommunication systems based on dense dispersion management. Moreover, we analyze some of actual implementation issues such as slope compensation scenario, junction losses, polarization mode dispersion and chromatic dispersion fluctuations.

Composite performance indicators of steganographic systems are investigated, on the basis which a new approach to construction covert channel models in telecommunication communication networks is proposed. Analytical expressions obtained for estimating maximum value bandwidth when introducing counteraction method and changing packet lengths, allow determining characteristics data hiding system.
