Irregular MDS Array Codes With Fewer Parity Symbols
Cheng Chen, Sian-Jheng Lin, Nenghai Yu · IEEE Communications Letters · 2019
An irregular MDS array code is a class of array codes allowing unequal sizes of each columns. In this paper, two classes of irregular MDS array codes are proposed to reduce the number of parity symbols at certain cases. The first code is based on polynomial remainder codes, and the second code uses the code bundling method. In addition, a systematic encoding approach of the polynomial remainder code is also presented.
