Hierarchical Network Synchronization of STAR Network based on TDMA

In this paper, we propose the hierarchical network synchronization scheme that is backward compatible for the existing commercial system, efficient for total system performance, and whose hardware modification is minimized. This system performance is, the relationship among bandwidth efficiency, complexity and MODEM performance, and superiority of network system applicability. The proposed structure can remedy the high hardware complexity and the lower ∙제1저자 : 윤주현 ∙투고일 : 2013. 10. 30, 심사일 : 2013. 11. 19, 게재확정일 : 2013. 12. 24. * 인하대학교 전자공학과(Dept. of Electronics Engineering, Inha University) * 과학기술연합대학원대학교 디지털방송공학부(Digital Broadcast Engineering, University of Science and Technology) * 삼성탈레스(주)(Samsung Thales) 78 Journal of The Korea Society of Computer and Information January 2014 accuracy of network sychronization that the existing satellite communication terminal system in the star network based on TDM/MF-TDMA of DVB-S2/RCS standards has. Besides, It has high efficiency in view of cost and system performance if the system designed for satellite broadcast requires system upgrade. In the body section, its hardware complexity and system performance of the proposed algorithm is analysed theoretically and treated with the related parameters(symbol rate, spreading factor, etc.) and the BER performance of control channel through the computer simulation for its verification that it can be applied for communications system. ▸
