基于LabVIEW的信道编码系统设计与实现

摘要

This paper describes the channel coding, analyzes the principle of linear block code represented by BCH code. Based on theoretical research and with LabVIEW software, the design and simulation of corresponding system is implemented, including coding, decoding and error detection function of linear block code and BCH code. Meanwhile, the analysis on error rate may make the resulted system become more perfect. Finally the friendly human-machine interface is built up via the front panel of LabVIEW.%针对信道编码,分析和介绍线性分组码及其重要的BCH码的相关原理.在理论研究的基础上,通过LabVIEW软件,实现相应的系统设计与仿真,如实现线性分组码、BCH码的编码功能、译码功能及纠查检错功能.实现相应功能的同时,进行误码率分析,使得到的系统更具全面性.最后,为了得到便于操作的人机界面,通过LabVIEW软件的前面板搭建其人机交互界面,得到了利用控件的选项板.
