Equalization methods in OFDM and FMT systems for broadband wireless communications

IEEE Transactions on Communications, 2002
Multicarrier systems are adopted in several standards for their ability to achieve optimal performance in very dispersive channels. In particular, orthogonal-frequency division multiplexing (OFDM) and filtered multitone (FMT) systems are two examples where the modulation filter has an ideal rectangular amplitude characteristic in time and frequency ...

HEO Satellite Systems for Broadband Aeronautical Communications

21st International Communications Satellite Systems Conference and Exhibit, 2003
* Formerly with Alenia Spazio SpA ABSTRACT Aeronautical broadband services provision by satellites is becoming a reality moving from an experimental base to operativity. Current systems are planned to lease capacity from existing geosynchronous (GEO) satellites in order to reduce upfront investments.

Developing a system concept and technologies for mobile broadband communications

IEEE Personal Communications, 1995
The mobile broadband system (MBS) concept is basically to extend, to mobile users, access to the range of broadband services which will exist for fixed users. This implies the establishment of a universal system architecture, capable of cost effectively handling a wide range of equipment with diverse service attributes, in a wide range of applications,

An operating system suited for integrated broadband communications networks

[1991] Proceedings 16th Conference on Local Computer Networks, 2002
Broadband communications technologies are close to maturity. Substantial changes can be therefore anticipated in the software architecture of next-generation computer networks. The consequences will be numerous. Amongst them, the classic separation between local- and wide-area networks is bound to become impractical under future circumstances.

Stochastic Modeling in Broadband Communications Systems

2002
From the Publisher: Mathematical methods based on the theory of stochastic processes have long been used effectively in telephone traffic modeling. Today's modern network traffic, which is distinctly different from traditional voice traffic, generates challenging mathematical and statistical problems.
