Mixed channel resource allocation analysis

Concepts of operation for SHF DSCS MILSATCOM are currently evolving to allow a mix of ECCM, FDMA and TDMA/DAMA traffic in the same transponder. Techniques for analyzing supportability for scenarios with a mix of ECCM and FDMA traffic have been developed. However, to support DAMA operation, techniques are needed for allowing quick allocation of satellite resources in mixed channel scenarios, with hierarchical arbitration and guaranteed supportability. This paper analyzes the hierarchical resource allocation problem in mixed channel scenarios for the case where all time slots in any TDMA waveform have approximately the same amplitude. The paper determines the parameters needed by the central controller in making allocation decisions and the resources that need to be allocated. The relationship between the level of allocation of these resources and network supportability are also determined along with the required uplink EIRP for each transmission. The hierarchical allocation of resources for DAMA operation in mixed channel scenarios is possible using the techniques described in this paper
