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)

  • 七自由度车辆数学模型
    说明:  汽车bai的7自由度模型du一般是在设计汽车悬架时用zhi到,1/4悬架时2自由度模型,包括簧上部分的dao垂直运动和簧下部分的垂直运动,半车悬架是4自由度模型,整车用7自由度模型。考虑汽车悬架作用,这车车身有三个自由度,分别是车体的Z轴上下运动,沿X轴和Y轴的转动。对于空间刚体6个自由度中的其他3个自由度,2个平动和转动与悬架系统无关,所以没有考虑。上述3个车身自由度加上4个悬架的簧下部分(主要是轮胎的上下跳动),一共是7个自由度。(The 7-DOF model Du of automobile Bai is generally a 2-DOF model when designing automobile suspension, including the vertical movement of Dao on the spring part and the vertical movement of the under spring part. The half car suspension is a 4-DOF model, and the whole car is a 7-DOF model. Considering the function of automobile suspension, the car body has three degrees of freedom, which are the up and down movement of Z axis of the car body, and the rotation along X axis and Y axis. For the other three of the six degrees of freedom of the space rigid body, two translation and rotation are independent of the suspension system, so they are not considered. The above three body degrees of freedom plus the four suspension spring parts (mainly the up and down runout of tires), a total of 7 degrees of freedom.)
