中文摘要
近年来，随着现代通信的发展，高速信息传输和高可靠性传输成为信息传输的两个主要方面，其中可靠性尤其重要。因为信道状况的恶劣，信号不可避免会受到干扰而出错。为实现可靠性通信，主要有两种途径：一种是增加发送信号的功率，提高接收端的信号噪声比；另一种是采用编码的方法对信道差错进行控制。
本设计就是针对差错控制编码中常用的卷积编码进行了原理分析，采用LabVIEW软件对其相应的模块设计与仿真，并最终设计与仿真实现卷积编码、维特比（Viterbi）译码、模拟信道过程。最后通过LabVIEW前面板搭建的人机交互界面，实现了利用控件选项板提供的各种控件来编辑便于操作的人机界面。

Abstract
In recent years,with the development of modern communications,two main aspects of the information transmission are high-speed information transmission and high reliability transmission,which reliability is especially inevitably be subject to interference and error because of the poor channel order to achieve reliable communication, mainly there are two ways:one is to increase the power of the transmission signal,improving the signal to noise ratio of the receiving end; another control using the method of encoding the channel errors.
This design analyzed the principle of Convolutional coding which is a common code of the Error control is mainly used the LabVIEW software to take the design and simulation. And it is successfully to design and simulate the process of Convolution coding,Viterbi decoding and Analog channel in the end. Finally,this design uses the LabVIEW to build a MSMMI which use controls all kinds of control to provide options board editor.
