In this paper, an efficient power control based MF-TDMA resource allocation scheme is proposed for next generation military satellite communication systems. The proposed scheme has the flexibility is used to support heterogeneous terminals with differ in transmission capabilities. The method can be divided into two parts : burst size calculation and burst structure determination. At first, we estimate the link budget taken into account a dynamic satellite link state variation. Then, applicable ACM level and burst size is chosen. In burst structure determination phase, we reorganize the burst structure in time-frequency domain by controlling limited power, bandwidth, time resources. In particular, we compensate the power spectral density among different terminals to integrate them in same transponder, Furthermore, we increase the packing efficiency by controlling the ACM level of the burst in applicable power spectral density range. Simulation results show that the method increase the spectral efficiency and burst packing efficiency. In addition, slot allocation rejection ratio is successfully reduced.주저자：국방기술품질원 품질경영본부,

Demand Assigned Multiple Access (DAMA) is a technology used to assign link capacity based on user demand. The allocation of capacity is limited by a set of constraints (e.g., priority of the traffic, link condition, RF interference, required bandwidth). Capacity is allocated in the time and frequency domains. An allocation algorithm determines per-user capacity for each assignment epoch. A packing algorithm assigns the actual time and frequency slots.Ideally, packing and allocation should be done jointly. However, these problems are generally solved separately due to computational complexity. This paper discusses the analysis of packing efficiency for a DAMA scheme that jointly considers packing and allocation. A mathematical programming model is applied to both a representative tactical radio network and a satellite network to determine packing efficiency. An allocation scheme is then derived from the packing efficiency. Packing overhead and traffic dropping probability are then calculated for the satellite case, assuming a uniform distribution of traffic per user. This enables us to determine how much traffic can be handled by a DAMA network without exhibiting excessive traffic loss.

Korean military is developing the next generation military satellite communications system in order to achieve the requirements of future military satellite communication such as high speed, high capacity, survivability, all IP networking, and on-the-move. In this paper, we survey and analyze the research interests about optimal resource allocation and IP networking such as MF-TDMA, random access, satellite IP routing, and PEP. Conventional researches have focused on the increase in channel throughput and efficiency. In addition to these measurements, we consider heterogeneous satellite terminals, full mesh topology, distributed network, anti-jamming, and the like which are the special characteristics of the next generation military satellite communications system. Based on this, we present key research issues and evaluation on the issues by simulation.
