This paper presents an overview of the results of the development of Ku-Band Low-Profile antennas for Mobile Satellite Communications. The antennas are based on a hybrid mechanical-electronic steerable array architecture. Different prototypes have been developed and demonstrated. We present the results for two receive-only antennas for satellite broadcasting applications and two Transmit-Receiv...

This paper deals with the second part of the latest digital TV standard DVB-SH (Digital Video Broadcasting – Satellite to Handhelds) with focus on utilization of its advantages for the next generation of mobile TV broadcasting. In the second part the simulation model of DVB-SH-B, which is using satellite configuration with TDM (Time Division Multiplexing) transmission mode, is presented. The wo...

This document describes the MIB module for the Digital Video Broadcasting Return Channel via Satellite system (DVB-RCS), as defined by the SatLabs Group. It defines a set of MIB objects to characterize the behavior and performance of network-layer entities deploying DVB-RCS.

Cellular phone users in Korea can watch TV using their mobile phones. The new multimedia service for the mobile users is called Digital Multimedia Broadcasting (DMB). DMB is a process of broadcasting multimedia over the Internet or satellite that can be tuned in by multimedia receivers or players. There are two competing DMB technology standards in South Korea: Terrestrial DMB and Satellite DMB...

Satellite networks provide a wide range of coverage throughout the globe and play very important role due to their broadcasting capacity bandwidth flexibility [...]

Satellite-terrestrial (ST) networks, in which many nodes are interconnected by both satellite and terrestrial networks, can efficiently support multicast services. This is because satellite broadcasting is suitable for a large multicast group and a terrestrial network is suitable for a small multicast group. An ST network requires a multicast routing algorithm that can select the appropriate sa...

For the design of satellite links, detailed knowledge of the transmission characteristics is important. Development issues such as channel measurements, feasibility and performance studies, pre-operational demonstration and veriica-tion tests, et cetera, are necessary or desirable before launch. For this task, another satellite might be used eventually. However, if a suitable satellite is not a...
