电话计费器程序/*信号定义： clk： 时钟信号，本例中其频率值为1Hz； decide： 电话局反馈回来的信号，代表话务种类，“01”表示市话，“10”表示 长话，“11”表示特话； dispmoney： 用来显示卡内余额，其单位为角，这里假定能显示的最大数额为50 元 （500 角）； disptime： 显示本次通话的时长； write,read： 当write 信号下降沿到来时写卡，当话卡插入，read 信号变高时读卡； warn： 余额过少时的告警信号。本例中，当打市话时，余额少于3 角，打长 话时，余额少于6 角，即会产生告警信号； cut： 当告警时间过长时自动切断通话信号。 */-telephone billing for procedures/* signal definition : clk : clock signal, which in this case, their frequency of 1Hz; decide : Telephone Bureau feedback signal, then the Treasury representative types, "01" Urban said, "10" The point said, "11" expressed special words; dispmoney : to show the card balance, the unit of angle, Here are supposed to show the maximum amount of 50 billion yuan (500 angle); disptime : The calls show the length; write, read : When the write signal arrival of the down time to write cards, When the card insert, read signal change high Reader; warn : Fees balance of the alarm signal.

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.
