A resource allocation approach for a joint occupancy of mixed waveforms in the same transponder

An important challenge for network planners and operators is to satisfy increasing demands for capacity given limited resources. Joint occupancy of many traffic types on the same transponder can be used to improve utilization efficiency. This paper presents an analysis for the joint occupancy of various anti-jamming spread spectrum networks and jamming-unprotected FDMA services in a single satellite transponder. The analysis determines a transponder operating point that provides satisfactory performance for FDMA services in the benign environment and ensures acceptable performance for spread spectrum networks in anticipated jamming threats. The paper also discusses transponder power capacity, frequency assignment, and terminal transmit power resource to assess the supportability of a transponder loading scenario. Input power levels referenced at the transponder input are determined for each transmission link to meet bit-error-rate (BER) requirements. The paper then describes a flexible resource allocation approach applicable to distributed control of networks in the joint occupancy transponder and provides insights useful to resource planning. The approach is proposed for military bent-pipe satellite transponders; it is also applicable to commercial bent-pipe satellites with some modifications
