说明：  在探讨D2D 对通信技术未来发展的导向作用基础上，明确了影响D2D 系统设计的多个因素，即D2D 设 备发现、资源分配、缓存技术、D2D-MIMO。从而勾画出基于D2D 技术的光纤前传和软件定义网络实现数据/控制分离的扁平化5G 架构，提出负责接入的下层宏/小基站蜂窝网和负责管理的上层网络云的管理机制。将D2D技术、SDN 技术、边缘计算和物联网技术等关键技术引入未来移动通信网络已经成为研究领域的热点，针对与之相关的、未来大规模网络的移动性、QoS 和大数据特性进行了讨论。(On the basis of discussing the guiding role of D2D in the future development of communication technology, this paper makes clear the factors influencing the design of D2D system, namely D2D hypothesis Standby discovery, resource allocation, caching techniques, d2d-mimo.Thus, the flat 5G architecture for data/control separation is outlined based on D2D technology of optical fiber prepreel and software-defined network, and the management mechanism of the lower macro/small base station cellular network responsible for access and the upper network cloud responsible for management is proposed.The introduction of D2D technology, SDN technology, edge computing and Internet of things into the future mobile communication network has become a hot topic in the research field.)

matlab中用牛顿迭代法求解非线性方程组。(The Newton iteration method is used to solve the nonlinear equations in MATLAB.)

非常适合新手入门的一本教材！可以更快的进入java领域！！！(A very suitable textbook for beginners! Can enter the field of Java faster!!!)

说明：  可以对HPA产生的非线性进行预失真，有效线性化数据(Use for DPD in HPA nolinear)

1、客户数据从Excel或Access中导入 2、数据量比较大，约200多万条记录 3、实现分地区查询 4、实现其他条件查询 （关键字） 5、实现分地区查询的用户权限限制，即特定用户只能查找特定地区的客户信息（显示）(1, the customer data from Excel or Access to import 2, larger than the data, about 10,000 more than 200 records of 3, to achieve sub-region query 4, the realization of other conditions query (keyword) 5, to achieve sub-region query user rights restrictions that particular user can only search a specific area of customer information (show))

链表，递归结构，结构指针变量，将链表数据从尾到头打印出来(List, recursive structure, the structure pointer variable, data from the end of the list printed Daotou)

基于STM32实现电子时钟的设计，可以通过按键、或者串口来进行时间设置(STM32-based electronic clock design, can be key, or serial port to set the time)

非常稳定的驱动注入Dll到进程的程序，功能强大，兼容性强。(Very stable drive into the process of Dll program, powerful, strong compatibility.)
