代码说明:

在LTE系统中通常采用多输入、多输出技术,主要原因是它能够使系统的信道容量得到明显提高,通过MIMO技术在LTE的下行链路中就能够实现。但是,在用终端只安装了一根天线,此时在LTE系统中无法运用传统的MIMO技术。综上所述,为了大幅度的提升上行链路的容量,必须把几个用户联合起来组成虚拟MIMO。用户配对算法性能的高低直接影响着虚拟MIMO系统的性能。本文主要对LTE系统中的虚拟MIMO用户配对算法进行研究。本文主要做了如下工作:首先研究了LET系统上行虚拟MIMO系统的模型,重点介绍了该系统的主要技术。接着对常用的几种类型的用户配对算法进行了分析,并利用软件对它们做了仿真。在此基础上提出一种

You canprogram mouse buttons to work in non-standard ways, as you mightwant to if you are left-handed. For simplicity, the left-hand hutton(under your forefinger if you are right-handed) is called the leftbutton, and the one on far right is the right mouse button. You willprobably find the terms intuitive once you use these buttons a fewtimesPoint and click; Right clickTo choose an item with the mouse, first move it on your desk until thearrow cursor is on that item; you are now pointing" at the item. Next,ress and release the left bu tton thlled"clicking " Point-andclick is the most common action you will make with your mouseally, click" refers to a lefise button clickYou can sometimes use your right mouse button to access or entercommands. In the 3d Modeler for instance, a right mouse buttonclick causes a short menu of commands to appear at the moustcursor. Generally, right click "refers to a right mouse button clickDouble-ClickOccasionally you may want to sclect all of thc text in a box,orperform a special lask(such as indicating the end of drawing a linewhile you are using Maxwell 3D. You can do this efficiently byquickly clicking twice with your left mouse button -a doubleDragging objects; Click and HoldWhen you are drawing in the 3D Modeler, you can often use yourmouse to enter objects and move around the screen. Frequently, youwill click the mouse button and hold it down until the next part of thecommand is reached (the object is oved, the next point is enteredand so forth).
