摘要

针对多小区大规模多输入多输出（MIMO）系统中存在的导频污染问题，通过分析MMSE信道估计产生的误差，提出了一种动态导频分配方案。该方案将目标小区与相邻小区相邻的边缘区域内的用户进行动态导频分配，剩余区域内的用户进行随机导频分配来提升系统下行链路的平均可达和速率。仿真结果表明，该方法不仅能显著地提升信道估计的性能，而且还能有效地提高整个系统下行链路的可达和速率。

Abstract

In order to solve the problem of the pilot contamination in multi-cell massive multiple input multiple output (MIMO) system

a dynamic pilot allocation scheme was proposed by analyzing the error of MMSE channel estimation.Users living in the fringe regions between the target cell and adjacent cells adopt the dynamicpilot allocation scheme

the rest of users are randomly pilot allocation to increase the average achievable sum rate of the downlink.The simulation results show that the proposed method can not only apparently improve the performance of the channel estimation

but also effectively improve the achievable sum rate of the downlink in the whole system.
