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.

ZD-BS是一个基于asp+access的个人blog系统
程序特点:
1.数据结构合理,执行效率高
2.缓存优化,在资源和效率上充分考虑平衡
3.可定制能力强,并不是傻瓜式系统,如果需要,用户应当修改源码(参考下面使用说明)
4.开源,免费
用户admin密码admin
编辑注:这个版本是无数据库的,所以只能升级不能重新安装,(为方便新使用朋友在data目录下的数据库为1.2的可以正常使用.)只需要把原来zd-bs的数据库复制进去就可以了,链接参数等请修改config.asp。在IE6下后台的表格可能会出现width100%的bug-ZD-BS is based on asp+ Access personal blog system program characteristics: 1. A reasonable data structure to implement high efficiency 2. Cache optimization, efficiency in terms of resources and take full account of the balance 3. Customizable ability, not a fool system, if required, the user should modify source code (refer to the following instructions) 4. open source, free user admin password admin edit note: this version is no database, we can only upgrade can not be re-installed, (For the convenience of the new use friends in the data directory of the database for normal use can be 1.2.) only to the original database zd-bs copy into it, modify the link parameters config.asp. In IE6 the backgrou
