| Abstract: | The theories and applications of the Grid Matrix 2D barcode and the error correcting code is described.By using improved Berlekamp-Massey,chien,Forney and the one error correcting algorithms,fast and accurate reed-Solomon code in GM barcode is achieved.At the same time the computing rules and algorithms in Galois field GF(27) are give,and the efficiency of encoder and decoder is improved.Meeting the demand of the performance and the practical applications,a complete solution is provided for the GM 2D error correcting barcode. |
