(CNN Student News) -- February 26, 2014

THIS IS A RUSH TRANSCRIPT. THIS COPY MAY NOT BE IN ITS FINAL FORM AND MAY BE UPDATED.

CARL AZUZ, CNN ANCHOR: This is the CNN STUDENT NEWS. Welcome to Wednesday show. I`m Carl Azuz, reporting from Atlanta. Venezuela is one of three divided countries we`ve told you about recently. It`s seeing protests against its president, rallies in support of him and violence in the upheaval. Its current leader like its previous one has been controversial. H

TD—LTE基站发射机ON／OFF功率测试方法

【摘要】TD-LTE基站发射ON/OFF功率用于衡量发射时隙对关闭时隙的干扰。本文描述了ON/OFF功率的测试装置和方法，阐述了测试硬件组成和限幅器的选用，对于测试中的同步机制作出了介绍。结合实际测试应用，给出了测试结果。

【关键词】TD-LTE发射机；ON/OFF功率；测试装置

3G移动通信系统TD-LTE的频谱利用率高，上下行非对称传输，正在得到越来越多的应用，通信基站越来越密集，对于TD-LTE基站发射机ON/OFF功率测试要求也越来越高，以避免通信系统内的干扰和基站自身的干扰，保证非对称的发射和接收。

1.ON/OFF功率和要求

TD-LTE基站发射与接受共享无线频率，采用时分复用，物理层帧长10ms，每帧包括10个子帧。为满足移动数据的不对称需求，下行和上行子帧可以灵活配置。3GPP定义了7种配置，以配置3为例，帧结构如图1，子帧1是特殊子帧，包括DwPTS、UpPTS和保护间隔；子帧0、5、6、7、8、9是下行，它和DwPTS属于发射机的发射时隙；而子帧2、3、4是上行，它和UpPTS、保护间隔属于基站发射机的关断时隙。发射时隙用于下行信号传输，关断时隙用于上行信号传输。

如何使我们不为穷人的存在而内疚

1.我想认真地思考人类最古老的一种活动，这项活动持续了多年，实际上已经超过了几个世纪，那就是尝试怎样使我们不为穷人的存在而内疚。??

2.贫穷和富有从一开始就共生在一起，彼此很不愉快有时还充满危险。普鲁塔克说：“贫富失衡乃共和政体最致命的宿疾。”富有和贫穷持续共存产生的问题，特别是如何证明在其他人还贫穷时我们富有是有道理的这一问题。成为有思想有学问的人几百年来孜孜不倦地思考探索的问题。

3.《圣经》提出了最初的解决之道：在现世遭受贫穷的人来世会得到更好的回报。他们的贫穷是暂时的灾难：如果贫穷但却能顺从，他们将来就会成为世界的主人。在某种程度上这就是最理想的解决方法。这样一来，富人就可以一边嫉妒穷人的美好前途一边享受他们的财富。

4.很长时间之后，即在1776年《国富论》发表二三十年之后——在英国工业革命开始之后——贫穷不均的问题及其解决办法开始具有了现代的形式。杰里米?本瑟姆，这位与亚当?斯密几乎是同时代的人，提出了这样一种准则，在某种程度上，美国人认为这一准则在英国几乎50年来一直影响显著，这就是实用主义学说。“通过实用的原则，”本瑟姆在1789年指出，“也就是在每次行动中，依照政党各方利益受影响的好坏趋势，
