Abstract:

The coding and modulation scheme of FDMA satellite communication systems is dynamically variable. Therefore balancing utilization of power and bandwidth can improve efficiency of resource usage and avoid decrease of system capacity due to limitation of power or bandwidth when allocating resources for subsequent users. In this paper, a game model with a dynamically variable coding and modulation mode is established based on an analysis of the satellite link. An algorithm for balanced utilization of power and bandwidth is developed to improve efficiency of system resource. Simulation results show that the proposed algorithm can improve the system channel capacity when system resources are limited.

Key words: balanced utilization ofpower and bandwidth, dynamic coding and modulation mode, game theory, resource allocation, satellite communication system
