提出了一种基于势能博弈的自适应分布式功率分配算法,将带有惩罚因子的多小区子带容量作为效用函数,把一个全局优化的问题转化成一个多次迭代的局部优化问题,通过梯度投影准则动态地对每个资源块理性地分配功率,达到协调小区间干扰、提高系统容量和降低时间成本的目的.仿真结果证明,该算法有效地降低了系统容量损失,改善了小区边缘用户的吞吐量. An adaptive distributed power allocation algorithm based on potential energy games is proposed. Taking the capacity of multi-cell subband with penalty factor as utility function, a global optimization problem is transformed into a multi-iteration local optimization problem. Through gradient The projection criterion dynamically allocates power to each resource block dynamically to achieve the purpose of coordinating inter-cell interference, improving system capacity and reducing time cost.The simulation results show that the algorithm effectively reduces the system capacity loss and improves the performance of users Throughput.
