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.

1．在选择装入背包的物品时，对每种物品I只有两种选择，即装入背包或不装入背包。不能将物品I装入背包多次，也不能只装入部分的物品I。 2．物品的种数，重量、价值，背包的容量要求输入； 3．算法中加入剪枝函数（对重量已经超过限制重量的子树不搜索）； -1. In the selection of the items into the backpack, for each of the items I have only two choices, that is loaded or not loaded backpack backpack. Items should not be many times I load backpack can not only part of the goods loaded I. 2. Number of species items, weight, value, capacity backpack for the importation 3. Algorithm to add pruning function (of weight over the weight limit does not search sub-tree)
