摘要/Abstract

摘要：

在编码调制方式动态可变的FDMA卫星通信系统中，通过功率和带宽的均衡利用可提高资源利用效率，并能防止后续用户分配资源时功率或带宽受限而导致的系统容量降低.对卫星链路进行分析，建立基于编码调制模式动态可变的博弈模型，提出一种基于功率和带宽均衡利用的编码调制模式分配算法，提高了系统资源的利用效率.仿真表明，所提出的资源分配算法在资源受限情况下能显著提高系统信道容量.

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
