A Control Architecture for a Military SSMA Satellite Communication System

As the prospect of full scale implementation of SSMA satellite communication systems approaches, methods will have to be developed to allow coexistence with other users employing different carrier modulations in a shared satellite transponder as well as graceful transition from a benign to stressed condition. The problem is magnified as communication density increases. This paper addresses a method for automatic control of the allocation of transponder resources to optimize throughput in accordance with user priorities and jamming level, and attempts to justify its use. The model employed assumes a mix of QPSK and direct sequence SSMA links. It also includes a simulation of system elements which can be used as a basis for accessing system capacity and exercising well-disciplined control to assure that the system delivers expected communication capacity.
