摘要
针对新型RAN架构无线接入网中功率分配问题进行研究,建立系统容量最大化的最优化数学模型,提出了一种基于RAN架构无线接入网的系统容量最大化的功率分配算法,并且应用人工鱼群算法求解了算法中目标函数的全局最优解,即一组使系统容量最大化的发射功率。仿真结果表明,与现有的分布式网络架构中非合作的功率控制博弈算法相比,新算法可以显著提高系统容量,即证明了该算法的有效性。
According to the power allocation problem based on the RAN architecture of the wireless access network, this paper built system capacity maximization optimization mathematical model, and put forward a power allocation algorithm with respect to maximization of system capacity based on the RAN architecture of the wireless access network, also applied the artificial fish swarm algorithm to solve the global optimal solution of target function in this algorithm, namely a group of transmitting power made the system capacity maximum. Simulation results show that compared with the existing non-cooperative power control game and pricing algorithm in distributed network architecture, the new algorithm can significantly increase the system capaci- ty. Thus.the simulation analyses conclude that the algorithm is effective.
