摘要
针对自组织网络(self-organizing network,SON)基站自动配置、自优化、自修复等优点,在深入研究遗传算法的基础上,提出了一种基于遗传算法的SON功率控制。通过划分频带和设置门限值来做到小区的功率控制,并提出了小区中心用户和边缘用户不同的SINR(signal to interference plus noise ratio)计算公式。为了更好地解决最佳门限值的设定,还提出了控制门限值的函数。通过建立遗传算法流程,对门限值函数和目标SINR值进行了寻优。仿真结果表明,该算法能够很灵敏地做到最佳门限值的搜寻,同时搜寻结果也符合相关理论的验证。
A kind of SON power control on account of genetic algorithm was put forward in this article based on studying genetic algorithm in-depth,which is according to the advantages of SON（self-organizing network） like base station auto-layout,self optimization and self-repairing,etc.It accomplishes the power control of village via dividing frequency and installing threshold value,and it also puts forward respective SINR design formulas of central and edge users in a village.For the sake of setting the optimal threshold value better,the function on controlling threshold is put forward.After that,it is searched that the threshold function and the target SINR via building genetic algorithm.The simulation result indicates that this algorithm can search for the optimal threshold sensitively and the result coincident with the proving of relative theory.
