ABSTRACT

In this paper, we propose the hierarchical network synchronization scheme that is backwardcompatible for the existing commercial system, efficient for total system performance, and whosehardware modification is minimized. This system performance is, the relationship amongbandwidth efficiency, complexity and MODEM performance, and superiority of network systemapplicability. The proposed structure can remedy the high hardware complexity and the lower accuracy of network sychronization that the existing satellite communication terminal system inthe star network based on TDM/MF-TDMA of DVB-S2/RCS standards has. Besides, It has highefficiency in view of cost and system performance if the system designed for satellite broadcastrequires system upgrade. In the body section, its hardware complexity and system performance ofthe proposed algorithm is analysed theoretically and treated with the related parameters(symbolrate, spreading factor, etc.) and the BER performance of control channel through the computersimulation for its verification that it can be applied for communications system
