基于最优功率分配原则的无线网络D2D用户通信质量分析

Wireless network D2D user communication quality analysis based on optimal power allocation principle

构建了一种基于最优功率分配原则的D2D用户通信质量分析算法,能够促进通信网络吞吐量获得明显提高,从而为D2D用户提供最佳资源分配方案。研究结果表明:研究构建得到的资源分配算法实现了吞吐量的显著提高,表现出比其它两种算法更优的计算性能。当D2D用户不断变多后,所有算法都获得了更高的吞吐量。在同样的D2D用户数情况下,采用资源分配算法可以获得比其它算法更优的运算性能。当最大发射功率提高后,吞吐量也明显上升,显著改善了算法性能。当蜂窝用户在系统中的最小速率需求持续提高后,将会引起整个系统出现吞吐量持续减小的情况。

A D2 D user communication quality analysis algorithm based on the optimal power distribution principle is constructed,which can improve the communication network throughput significantly and provide the best resource allocation scheme for D2 D users.The results show that the resource allocation algorithm constructed in this study achieves a significant increase in throughput,and shows better computational performance than the other two algorithms.As the number of D2 D users increases,all algorithms achieve higher throughput.With the same number of D2 D users,the resource allocation algorithm can get better performance than other algorithms.When the maximum transmitting power is increased,the throughput also increases significantly,which significantly improves the performance of the algorithm.When the minimum rate requirement of cellular users in the system continues to increase,the throughput of the whole system will continue to decrease.
