大规模MIMO系统研究进展
说明： 随着无线通信技术的快速发展和智能手机的迅速普及，人们对数据传输速率提出了更高的需
求。为进一步提高数据传输速率，通过增加基站天线数目构建大规模ＭＩＭＯ系统，是一种高效而相对
便捷的方式。大规模ＭＩＭＯ系统能深度发掘空间维的自由度，使得基站能够利用同一时频资源服务于
多个用户。本文探讨了大规模ＭＩＭＯ系统的导频污染问题及解决方案、适用于大规模ＭＩＭＯ系统的
信道模型以及低复杂度的传输技术与实现方法三项关键技术。与现有ＭＩＭＯ系统相比，大规模ＭＩＭＯ
系统能显著提高频谱效率、能量效率和系统的鲁棒性能。作为第五代移动通信（５Ｇ）最具潜力的研究内
容之一，大规模ＭＩＭＯ无线通信技术已引起国内外的广泛关注，但相关研究工作尚处在起步阶段，还有
大量的技术难点需要进一步突破。(so that the base station can use the same time-frequency resources to serve
Multiple users.In this paper, pilot frequency pollution of large scale MIMO system and its solution are discussed
Channel model, low complexity transmission technology and implementation method are three key technologies.Large scale MIMO compared to existing MIMO systems
The spectrum efficiency, energy efficiency and robust performance of the system can be significantly improved.As the fifth generation mobile communication (5G) has the most potential within the research)

AFDD
说明： 本文提出的自动频域分解是受到[1,2]引入的频域分解(FDD)的启发。目的是识别在环境噪声下土木工程结构健康监测中获得的加速度记录的振型、特征频率和模态阻尼比。(The automatic frequency domain decomposition proposed in this paper is inspired by the frequency domain decomposition (FDD) introduced by [1,2]. The purpose of this paper is to identify the mode shape, characteristic frequency and modal damping ratio of acceleration recorded in the health monitoring of civil engineering structures under environmental noise.)
