Resource Allocation Method of TDMA Satellite Communication System Based on Ant Colony Algorithm

卫星通信系统资源分配的合理与否直接影响到卫星通信系统整体效能的发挥。但目前TDMA卫星通信系统资源分配算法还存在计算复杂度较高、分配效率低下、求解时间较长等问题,针对TDMA卫星通信系统资源特点,在分析卫星通信系统资源分配目标函数的基础上,参考自然界蚂蚁群体觅食行为,通过蚂蚁行走的路径模拟TDMA卫星通信系统资源分配可行解,建立一种基于蚁群算法TDMA卫星通信系统资源分配模型,并运用MATLAB软件对TDMA卫星通信系统资源分配方法进行仿真验证。仿真结果表明可解决有限时隙资源条件下TDMA卫星通信系统资源分配问题,提高了资源分配算法的寻优能力,具有一定参考价值。

Reasonable resource allocation of the satellite communication system directly affects the overall effectiveness of the satellite communication system.However,the current TDMA satellite communication system resource allocation algorithm still has problems such as high computational complexity,low allocation efficiency,and long solution time.This article focuses on the resource characteristics of TDMA satellite communication system and analyzes the objective function of satellite communication system resource allocation.With reference to the foraging behavior of ant colonies in nature,a feasible solution for resource allocation of TDMA satellite communication system is simulated through the path of ants walking,and a resource allocation model based on ant colony algorithm is established,and MATLAB software is used to allocate resources.The method is simulated and verified,and the simulation results show that it can solve the resource allocation problem under the condition of limited time slot resources,improve its optimization ability,and have certain reference value.
