多用户MIMO系统用户选择算法
User selection algorithm for multi-user MIMO system
摘要
Abstract
MIMO (Multiple-Input Multiple-Output) system can improve spectrum efficiency effectively, and does not need to increase the bandwidth of the system. However, the existing pre-coding method and number of antenna make the accommodated users is a finite number, and can not meet the practical needs. To solve this problem, this paper presents a user selection algorithm with equal power allocation. The proposed algorithm gets the optimum user groups by the equivalent approximation of channel capacity. At the same time, in order to reduce the complexity of the user selection algorithm further, an iterative suboptimal user selection algorithm is proposed to select the optimum users fastly. The simulation results show that the algorithm can obtain better performance of the system capacity, and is suitable for the actual communication system.关键词
