The R&D in satellite communications in Korea has been driven mainly by KCC (Korea Communications Commission) but in a small scale compared to Korea space development program organized by MEST (Ministry of Education, Science and Technology). Public and civilian satcom sector R&D has been led mainly by ETRI with small/medium companies contrary to rare investment in private sector while military s...

Digital Video Broadcasting (DVB) is a standard defining a one-to-many unidirectional data network for sending digital TV programs over satellite, cable, and other topologies. The standard enables the broadcasting industry to offer hundreds of pay-TV channels to consumers. The expanded capacities make the broadcast signals more valuable and attractive to signal thefts [1]. To protect a DVB data-...

A hybrid data transmission technique for multimedia satellite broadcasting is proposed. The main-channel data and sub-channel data are simultaneously transmitted using QPSK modulation and 2ASK modulation, respectively, but the latter modulation timing is offset by half the main-channel QPSK symbol length in time. The BER performance in a Gaussian channel, the transmission bandwidth, and the tra...

This special issue of the Wiley International Journal of Satellite Communications and Networking hosts a selection of papers related to S-band mobile satellite R&D activities recently completed in the frame of the European Space Agency ARTES programs. The S-band allocation to hybrid satellite and terrestrial services in Europe 2009 and in other parts of the world has attracted operator, industr...
