一：问题描述 针对某个集体（比如你所在的班级）中的“人名”设计一个哈希表，使得平均查找长度不超过R，完成相对的建表和查表程序。 二：基本要求 假设人名为中国人姓名的汉语拼音形式。待填入哈希表的人名共有30个，取平均查找长度的上限为2。哈希函数用除留余数法构造，用伪随机探测再散列法处理冲突。 三：实现提示 如果随机函数自行构造，则应首先调整好随机函数，使其分布均匀。人名的长度均不超过19个字符（最长的人名如：庄双双（ZHAGN SHUANG SHUANG）。字符的取码方法可直接利用C语言中的tosacii函数，并可对过长的人名先作折叠处理。 四：需求分析 本演示程序是对哈希表的建立和查找进行演示，主要数据来自自己编写的人名“A~~Z”等字母组成，拼音由开头的字母组成的词组，查找时用伪随机探测再散列法处理冲突。随机产生人名的位置。具体的程序内容在源程序里面有比较详细的解析。程序的运行在下列有详细的介绍。 -one : Problem description against any collective (such as your own classes) of "names" design a hash table. you make the average length of not more than R, completes the construction and Lookup Table procedures. Two : the assumption that the basic requirements were known as the Chinese name of Chinese pinyin form. Hash Table question Enter the names of a total of 30, you take the average length of a maximum of two. Hash functions with a few exception I stay constructed using pseudo-random re-hash detection method to resolve disputes. 3 : Achieving suggested ra

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.
