摘要
TD-LTE网络基站选址优化是提高移动通信服务质量,降低建站成本的重要手段.首先概述了TD-LTE网络基站选址应该遵循的原则、目标和主要的方法以及所面临的困难,进而剖析了TD-LTE网络基站选址经典模型存在的一些不足,通过融合协同进化算法和人工免疫算法的优点,提出了一种新颖的TD-LTE基站选址优化协同进化免疫算法LCIA.仿真结果表明,与经典的协同算法和人工免疫算法相比,建站成本更低、网络覆盖率和网络容量更高,且具有更好的收敛性.
To improve the services-quality of mobile communication and reduce the cost of establishing stations,the location optimization of the TD-LTE network base station is an important means.Firstly,the principles,objectives,the main methods and difficulties of TD-LTE network base station location selection are summarized in this paper,and then some disadvantages of TD-LTE network base station location models are analyzed.By combining the advantages of co-evolution algorithm and artificial immune algorithm,a new TDLTE network base station location optimization co-evolutionary immune algorithm LCIA is proposed.Simulation results show that proposed algorithm has not only brought lower station-building cost and higher network coverage and capacity than the classical co-evolution algorithm and artificial immune algorithm,but it also has better convergence.
