Java EJB简单例子
Java EJB简单例子,这是HelloWorldBean的Home接口,它是EJB对象的生成库,无状态会话(将在下一个实例中具体讲解)Bean,这个接口是客户端与EJB对象相互作用的中间途径,通过Client触发调用Bean方法:
try {
//取得初始化属性jndiContext,它是连接JNDI树的起始点
InitialContext jndiContext = new InitialContext(properties);
//取得Home对象的引用
Object ref = jndiContext.lookup("HelloWorldHome");
HelloWorldHome home = (HelloWorldHome)
PortableRemoteObject.narrow (ref, HelloWorldHome.class);
//用EJB生成库Home生成EJB对象
HelloWorld hello= home.create();
//调用EJB对象方法printHelloWorld(),EJB对象把调用委派给Bean
System.out.println (hello.printHelloWorld());
}

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)
