In this paper a multi-statistics model of the impulse noise is presented. An impressive experimental noise data collection acquired from digital access loops provides the synthetic noise environment with the most convenient probability density functions. Internal and external impulse noise sources within communications copper lines are briefly surveyed. A… (More)
Atmospheric conditions can cause the terrestrial laser links fail. Some optical signal coding techniques are used to enhance the free-space optical systems robustness for tolerating certain atmospheric constraints. The terrestrial laser communications link survivability is appraised by measuring the bit error rate of the link.
The development and diversification of the electronic services, closely related to the exponential development of communication and information technologies-ICT, lead to fundamental change in the field of service activities. The electronic services allow continuous access of the citizen to public sources of information, changing the concept of organization… (More)
The diversification of telecommunication networks and advances in communication technologies, including the Internet, has considerable potential as an environment supporting telemedicine applications. Within eRomania government programme a special focus is on public and private electronic services development. During the last decade, communications systems… (More)
