The information coding is using element each in original matrix position as a cell to original matrix
It is encoded to form encoder matrix.Encoder matrix after coding is mutually closed with original matrix and corresponding merchandise news
Connection, forms one-to-one relationship.
In order to enable the element of each element in encoder matrix and surrounding to establish correlation, any the one of original matrix
Row or a column both ends are considered as Logic adjacent, so that becoming the figure being closed up and down on geometric position from original matrix.It is former
Each element position is considered as a cell in beginning matrix, and new element, the member in original matrix are added in each cell
Element is used as information bit, and new element is as check bit.
The element at least one original matrix is selected, the value of check bit should be as the case may be and by selection element
Distribution set up certain corresponding relationship.
For example, in encoder matrix, the value of check bit can be with position up and down around the cell in each cell
The element number association selected possessed by information bit in the cell set.It is selected for example, the check bit value is equal to
The number of element, or than being selected element number N big or small N(N is natural number).
For example, the value of check bit is letter in each cell in encoder matrix, with surrounding eight in the cell
It is associated in original matrix possessed by information bit by the number of selection element in cell or up and down four cells.When
When number is respectively 0 ~ 8, it is respectively A ~ H that check bit, which corresponds to value,.

A (1,3)=[A(3,3)+A (2,3)+X2+A (1,4)] mod X
A (2,3)=[A(1,3)+A (3,3)+X4+A (2,4)] mod X
A (3,3)=[A(2,3)+A (1,3)+X6+A (3,4)] mod X
A (1,5)=[A(3,5)+A (2,4)+A (1,4)+X1] mod X
A (2,5)=[A(1,5)+A (3,5)+A (2,4)+X3] mod X
A (3,5)=[A(2,5)+A (1,5)+A (3,4)+X5] mod X
Wherein, X is the element selected in original matrix, is herein 5；This equation group is solved, damaged information bit can be obtained
X1~X6。
Table 3
Damaged information number and position are uncertain in practical situations, therefore while establishing an equation should be according in step a
Operation rule traverses damaged grid peripheral information, and selection is answered in operation for decoding the most useful information, this process
It is repeated, until solving all damaged information codes.
If damaged information bit is excessive, will lead to the equation group listed cannot uniquely be solved, and also meaning that can only solve
