说明：  电力拖动系统及仿真的课件，直流调速，交流调速，同步电机，异步电机(Courseware of electric drive system and simulation)

一个虚拟仪器的程序，功能为保存图片数据到数据库。-A virtual instrument procedures, functions for the preservation of image data to a database.

说明：  使用此子程序定义非均匀的分布式机械负载（压力和体力）。 当负载是时间和/或位置的复杂函数时，通常使用用户子程序DLOAD。 通常可以用* AMPLITUDE选项建模简单的时间函数。 子程序也可以用来定义一个随元素号和/或积分点数而变化的负载。(This subroutine is used to define non-uniform distributed mechanical loads (pressure and physical force). When the load is a complex function of time and/or location, the user subroutine DLOAD is usually used. A simple time function can usually be modeled with the * AMPLITUDE option. Subprograms can also be used to define a load that varies with the number of elements and/or points of integration.)

本文首先概述了OFDM 的原理、特征和关键技术，介绍了系统需要的几种同步。然后就同步误差对系统性能的影响进行了简单的分析，表明定时偏差和采样频率偏差将会引入码间干扰，载波频率偏差导致载波间干扰的发生。因此，在OFDM系统接收机中定时的确定、载波频率偏差和采样频率偏差的纠正是信号恢复的关键。之后对OFDM系统同步的几种实现方法进行了介绍，分析了各同步方法的性能。-The paper first outlines the principles of OFDM, features and key technologies, the system needs to introduce several synchronization. Synchronization error and then the impact on system performance for a simple analysis, show that the timing deviation and the sampling frequency deviation will introduce inter-symbol interference, the carrier frequency deviation led to the occurrence of ICI. Therefore, in OFDM system receiver to determine the timing, carrier frequency offset and sampling frequency offset correction signal to restore the key. After the OFDM system to achieve synchronization of several methods of introduction, an analysis of the performance of the synchronization method.
