摘　　要：GMR-1卫星移动通信系统属于典型的带宽频率双受限系统,功率/带宽利用率是评价传输方案优劣的重要指标,提出了一种融合波束覆盖的无线信道动态分配算法,该算法充分利用卫星波束覆盖范围信息,并结合终端地理位置信息实时为用户分配信道资源。仿真结果表明,该算法相对于常规的DCA算法,功率、带宽利用率均有提升。The GMR-1 satellite mobile communication system is a typical bandwidth-frequency dual-limited system.Power/bandwidth utilization is an important indicator to evaluate the quality of the transmission scheme.This paper proposes a dynamic channel allocation algorithm with fusion beam coverage,which makes full use of satellite beam coverage information and terminal geographic location information to allocate channel resources for users in real time.Simulation results show that the proposed algorithm improves the power and bandwidth utilization compared to the conventional DCA algorithms.
