基于Reed-Solomon码的Data Matrix条码纠错研究

为了研究Data Matrix条码的纠错能力，首先介绍了Data Matrix条码的特点和Reed-Solomon码的基本概念；接着研究了Reed-Solomon码在DataMatrix二维条码中的应用，重点分析了Data Matrix二维条码中Reed-Solomon编、解码的基本原理与步骤，并用C语言实现它的编、解码算法；最后对Reed—Solomon码的纠错能力进行了测试。实验结果表明，Data Matrix二维条码采用Reed—Solomon码作为纠错码，可以有效地排除干扰并进行纠错。

Research of Data Matrix error correcting based on Reed-Solomon code

Aiming at studying the error-correcting capacity of Data Matrix barcode. Firstly, the characteristic of Data Matrix and the basic conception of Reed-Solomon code were introduced. Then an analysis of Read-Solomon codes application in two dimensional Data Matrix barcode was given, and the analysis of decoding algorithm of Data Matrix barcode error-correction was focused on. The basic principles and steps of Read-Solomon decoding were discussed in detail, and it＇s encoding and decoding methods in C language were realized. Finally, the error-correcting capacity of Reed-Solomon code was tested. The test results indicate that Data Matrix barcode uses Reed-Solomon code as error-correction, which can effectively correct lost or missing data for damaged symbol.
