Korea military satellite communications system is being employed since 2007 named ANASIS. Next generation military satellite communications system havs been developed for expanding capacity and survivability. Among the purposes, as for expanding capacity, the communications system require efficient technology to use limited resource. So, next generation communications systems are expected to use MF-TDMA technology based on DAMA and many kinds of research is in progress about MF-TDMA. MF-TDMA is the technology which has the advantages of FDMA and TDMA. By using MF-TDMA, communications system can use limited resource efficiently.
The performance of resource allocation depends on the allocation scheme. The purpose of resource allocation scheme is to use limited resource efficiently without waste in MF-TDMA frame.
In this paper, I proposed efficient resource allocation scheme for next generation military satellite communications system. First, I designed satellite communications system related to next generation military satellite communications system. Second, I applied existing resource allocation schemes to desinged satellite communications system, and analyzed performances. Third, I found disadvantages and limits about existing resource allocation schemes, and proposed efficient resource allocation scheme. Lastly, I compared and analyzed the performances of proposed resource allocation scheme such as Total Resource Efficient, Reject Ratio, Computational Time, PSD distribution with existing resource allocation schemes.
