基于补偿因子的D2D通信自适应联合功率控制算法
|
摘要
针对融合设备到设备(device to device, D2D)通信的蜂窝系统中路径损耗补偿因子单一、功率控制性能不佳等问题,提出一种自适应联合功率控制算法.根据D2D用户到基站及蜂窝用户的距离计算出路径损耗补偿因子增补量,得出D2D用户及蜂窝用户的路径损耗补偿因子矩阵,提升功率控制性能;同时采用联合闭环功率控制方式进一步降低D2D用户及蜂窝用户的同频干扰.实验仿真表明:相比于传统功率控制算法,该算法对系统的信干噪比(signal to interference plus noise ratio, SINR)有较好的提升作用,且吞吐量在1 000kbit/s以上的用户数量是传统功率控制算法的1.7倍.
An adaptive joint power control algorithm is proposed to improve the path loss compensation factor and the performance of power control in the cellular system incorporating device to device(D2D)communications. The added amount of the path loss compensation factor could be calculated according to the distance between D2D users to base station and cellular users, then the path loss compensation factor matrix of D2D users and cellular users could be used to improve the performance of power control. In order to improve the co-channel interference furtherly, a joint closed loop power control mode is adopted for D2D users and cellular users. Compared with traditional power control algorithms, simulation results show that the signal to interference plus noise ratio(SINR) of the system could be improved better by the proposed algorithm, and the number of users of the proposed algorithm whose throughput is more than 1000 kbit/s is 1.7 times of the traditional power control algorithm.
