Title:
METHOD FOR CONSTRUCTING REPAIR BINARY CODE GENERATOR MATRIX AND REPAIR METHOD
Document Type and Number:
WIPO Patent Application WO/2020/029418
Kind Code:
A1
Abstract:
Provided is a method for constructing a repair binary code generator matrix applicable to the field of improving digital processing techniques. The method for constructing a repair binary code generator matrix comprises: denoting a constructed code with C 1(k, r, d, p), where η ＝ d - k + 1, k ≥ 3, r ≥ 3 is an odd number, d ＝ k + (r - 1)/2 and τ ＝ (d - k + 1) k-2, a constructing matrix is denoted by P k
×
r and a calculation formula thereof expressed as formula (I). A regenerated code product matrix structure still works in a quotient ring, the computational complexity is low, and repair bandwidth is reduced with greater fault tolerance.
