Systematic MDS erasure codes based on vandermonde matrices [PDF]
IEEE Communications Letters, 2004 An increasing number of applications in computer communications uses erasure codes to cope with packet losses. Systematic maximum-distance separable (MDS) codes are often the best adapted codes.

New Two-Stage Automorphism Group Decoders for Cyclic Codes
IEEE Access, 2020 Recently, error correcting codes in the erasure channel have drawn great attention for various applications such as distributed storage systems and wireless sensor networks, but many of their decoding algorithms are not practical because they have higher

Hierarchical erasure correction of linear codes [PDF]
Finite Fields and Their Applications, 2020 Linear codes over finite extension fields have widespread applications in theory and practice. In some scenarios, the decoder has a sequential access to the codeword symbols, giving rise to a hierarchical erasure structure. In this paper we develop a mathematical framework for hierarchical erasures over extension fields, provide several bounds and ...

An Optimal Recovery Approach for Liberation Codes in Distributed Storage Systems
IEEE Access, 2020 To reduce the storage cost, distributed storage systems are gradually using erasure codes to ensure data reliability. Liberation codes, which satisfy the maximum distance separable (MDS) property and provide optimal modification overhead, are a class of ...

Efficient erasure correcting codes [PDF]
IEEE Transactions on Information Theory, 2001 Summary: We introduce a simple erasure recovery algorithm for codes derived from cascades of sparse bipartite graphs and analyze the algorithm by analyzing a corresponding discrete-time random process. As a result, we obtain a simple criterion involving the fractions of nodes of different degrees on both sides of the graph which is necessary and ...

Codes with locality for two erasures [PDF]
2014 IEEE International Symposium on Information Theory, 2014 In this paper, we study codes with locality that can recover from two erasures via a sequence of two local, parity-check computations. By a local parity-check computation, we mean recovery via a single parity-check equation associated to small Hamming weight.
