针对大规模MIMO系统导频污染问题,提出一种基于用户分类的动态导频分配策略。根据目标小区用户信号强度的方差设置合理的用户信号强度临界值,将目标小区用户分为中心用户和边缘用户。中心用户采用最大载干比算法分配导频,以最大化中心用户总信道容量。边缘用户采用贪婪算法分配导频,以提高每个边缘用户的信干噪比。仿真结果表明,所提策略在提高边缘用户信干噪比的同时能够有效提高系统的信道容量。
Aiming at the problem of pilot contamination in massive MIMO system
a dynamic pilot assignment strategy based on user classification was proposed.The target cell user was divided into the central user and the edge user based on the variance of target cell user signal intensity.The central user used the maximum C/I algorithm to assign pilots to maximize the channel capacity of the central user.The edge user used greedy algorithm to assign pilots to improve the signal to interference and noise ratio of each edge user.Simulation results show that the proposed strategy can improve the channel capacity of the system while improving the signal to interference and noise ratio of the edge user.
