Research of Data Matrix error correcting based on Reed-Solomon code
Zhan Hong-wu · Mechanical & Electrical Engineering Magazine · 2009
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.
