This contribution describes a modulation scheme suitable for satellite communication, which is based on FM and provides an increased bandwidth of 2 to 3 times that which is currently available commercially with QAM schemes. The system provides best advantage when used in high bandwidth links that occupy the whole transponder. This provides a potential throughput of over 400Mbits/s through a con...

Satellite communication systems play an important role in the deployment of a global communication infrastructure, and the increasing demand for frequency bands with large bandwidth availability to satisfy satellite communications applications requirements makes the exploration of higher and higher frequency ranges of a vital importance. In this paper, an introduction to the WAVE (W-Band Analys...

The performance of the Multicast Dissemination Protocol (MDP) in a simulated satellite channel is investigated. The environment that is modeled is that to be expected in a small satellite communications environment including channel errors and link interruptions. The satellite link is simulated with a channel environment simulator. The performance of MDP is compared with file transfer protocol ...

A novel model for the outage probability prediction in time diversity satellite communication (SatCom) systems operating above 10GHz is proposed. Due to the migration of operating frequency at Ka band and above, atmospheric phenomena affect the signal. Rain is the dominant fading mechanism. Diversity techniques are the probable solution of the compensation of rain fading. Among the diversity te...

The aim of this World Congress was to cover ‘all aspects of health and well-being in an aging population’, and thus included the integration of gender as a variable in biology, behavior, ethnicity, cultural values, environment and health-care utilization. The Congress aimed to reflect the world-wide challenge for those working in the field of mid-life medicine – not just to provide more efficie...

Recently the requirement of low-profile antennas for wireless communications has greatly increased the demand of microstrip antennas because of their low-profile and light weight characteristics. In this paper a miniaturized, multiband dualstacked probe fed microstrip antenna is presented. There exists S-shaped coupling structure between the patches and a wide ground slot to improve antenna cha...

This paper comes from the joint activity JA2350 ”Network Management and Security” of the SatNEx IST project. A major aim of the Satellite Network of Excellence (SatNEx) is to rectify the fragmentation in satellite communications research by bringing together leading European academic research organisations in a durable way. Especially the security research suffers from a great fragmentation wit...

This letter presents a novel and compact antenna array suggesting geometrical modifications in the concept of collinear arrays at millimeter-wave (MMW) spectrum. The extension of the standard narrowband Franklin linear antenna array in a compact two-dimensional (2D) assembly is proposed and multiband response is accomplished in this work which fulfills demands of future 5G systems. The proposed...

The flexibility of mobile wireless ad hoc networks (MANET) and global coverage of satellite communications presented an ideal combination to provide emergency and disaster relief services. This paper presented the concept of a hybrid MANET-satellite network developed in the on optimising hybrid ad hoc and satellite networks (MONET) project funded within the EU 7th Framework Programme (FP7). It ...

A new structure for isolator is proposed in this work. The proposed structure consists of metamaterial-magnetoplasma semiconductors parallel plate structure. The utility of magnetoplasma semiconductors is promising in developing nonreciprocal components in the submillimeter-wave and millimeter-wave bands for satellite communications. Metamaterials (MTMs) is used to enhance the behavior of the i...
