Asymptotically MDS Array BP-XOR Codes

Belief propagation or message passing on binary erasure channels (BEC) is a low complexity decoding algorithm that allows the recovery of message symbols based on bipartite graph prunning process. Recently, array XOR codes have attracted attention for storage systems due to their burst error recovery performance and easy arithmetic based on Exclusive OR (XOR)-only logic operations. Array BP-XOR...

Array Codes with Optimal Encoding

We present a new class of MDS array codes of size n n (n a prime number) called X-Code. The X-Codes are of minimum column distance 3, namely, they can correct either one column error or two column erasures. The key novelty in X-Code is that it has a simple geometrical construction which achieves encoding/update optimal complexity, i.e., a change of any single information bit a ects exactly two ...

Codes And Xor Graph Products

What is the maximum possible number, f3(n), of vectors of length n over {0, 1, 2} such that the Hamming distance between every two is even? What is the maximum possible number, g3(n), of vectors in {0, 1, 2}n such that the Hamming distance between every two is odd? We investigate these questions, and more general ones, by studying Xor powers of graphs, focusing on their independence number and ...
