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)

说明：  虚拟同步机技术是将分布式电源、电动汽车、储能以及负荷变流器模拟为旋转同步机的技术，使得电力电子变流器能够像同步机一样具有大电网的同步机制，从而实现电力系统的自主运行。虚拟同步机技术为解决集中式风光消纳、大规模分布式能源、电动汽车和储能为电力系统带来的一系列挑战提供了一条崭新的思路和解决方案。(Virtual synchronous machine technology is a technology that simulates distributed power supply, electric vehicle, energy storage and load converter as rotary synchronous machine. It makes power electronic converter have synchronization mechanism of large power grid like synchronous machine, so as to realize the autonomous operation of power system. Virtual synchronous machine (VSM) technology provides a new way of thinking and solution to a series of challenges brought by centralized solar energy absorption, large-scale distributed energy, electric vehicles and energy storage for power system.)

For advanced geometry, most apps will prefer to load pre-authored meshes from a file. Fortunately, when using meshes, D3DX does most of the work for this, parsing a geometry file and creating vertx buffers for us. This tutorial shows how to use a D3DXMESH object, including loading it from a file and rendering it. One thing D3DX does not handle for us is the materials and textures for a mesh, so note that we have to handle those manually.
