Systematic Encoding for Erasure Correcting Codes By Using Shift Operation And Exclusive OR
Yuta Hanaki, Takayuki Nozaki (Yamaguchi Univ.) IT2017-20
Abstract (in Japanese) (See Japanese page) 
(in English) Reliable distributed storage systems can be realized by erasure correcting codes.
In this paper, we propose a systematic and suboptimal erasure correcting code by using shift operations and exclusive OR.
Here, an erasure correcting code is suboptimal if it is always possible to decode from the same number of the encoded packets as the source packets, but the encoded packets are slightly longer than the source packets.
We refer the additional bits of an encoded packet, by overhead.
Moreover, this paper evaluates the total and maximum overheads and encoding complexity of the proposed code.
