摘要 优化基站导频功率对提高WCDMA系统的网络服务性能具有重要意义,为了解决WCDMA网络基站导频功率联合分配问题,给出了一个基于免疫优化算法的基站导频功率优化方案。设计了基站导频功率分配问题的数学模型,并利用免疫优化算法进行求解,最后与文献算法进行了对比实验。实验结果表明:本文算法方案能在可接受的运行时间内找到大型通信网络中导频功率分配问题的近似最优解,具有较好的应用价值。 To solve the base station pilot power allocation problem in WCDMA network, a solution based on immune clone algorithm was proposed. The mathematical model of base station pilot power allocation problem was expounded, the framework of immune clone algorithm was given, and simulation experiments were done to validate algorithm. Simulation result shows that the proposed algorithm can obtain the approximate optimal solution of base station pilot power allocation problem in large networks with an acceptable running time, and has the advantages of aood anolieation value.
