| 摘 要： | 针对大规模多输入多输出(MIMO)系统硬件复杂度较高以及基站所能支持的最大用户数受基站天线数影响的问题,提出一种计算复杂度较低的适应于大规模MIMO系统下行链路的联合天线选择与递减用户调度算法,通过移除“差”的天线和用户来最大化系统总速率,降低基站所需配置的射频链路数.仿真结果证明,该方案能够在保证系统性能的前提下大幅度降低系统硬件复杂度.

| Abstract: | A joint antenna selection and decremental user scheduling algorithm was given to solve the problem on high hardware complexity,and the maximum number of users affected by base station antennas for massive multiple-input multiple-output system was discussed.The scheme is to maximize the sum rate and reduce the number of radio frequency chains by removing the worst antennas and users.Simulations show that the proposed scheme can greatly lower the hardware complexity on the premise of guaranteeing the system performance. |
