From Linear Exact Repair to Mixed-Alphabet Codes: The Bandwidth-Subpacketization Tradeoff of MDS Array Codes
Zihao Zhang, Guodong Li, Sihuang Hu
MDS array codes achieve optimal storage efficiency in distributed storage systems, but their repair bandwidth depends critically on the sub-packetization level. While the theoretic…
Making Wide Stripes Practical: Cascaded Parity LRCs for Efficient Repair and High Reliability
Fan Yu, Guodong Li, Si Wu +2
Erasure coding with wide stripes is increasingly adopted to reduce storage overhead in large-scale storage systems. However, existing Locally Repairable Codes (LRCs) exhibit struct…
Optimal Repair of MDS Array Codes
Zihao Zhang, Guodong Li, Sihuang Hu
Maximum distance separable (MDS) codes are widely used in distributed storage systems as they provide optimal fault tolerance for a given amount of storage overhead. The seminal wo…
Constructing cooperative MSR codes with sub-packetization
Zihao Zhang, Guodong Li, Sihuang Hu
We address the multi-node failure repair challenges for MDS array codes. Presently, two primary models are employed for multi-node repairs: the centralized model where all failed n…
MSR Codes with Linear Field Size and Smallest Sub-packetization for Any Number of Helper Nodes
Guodong Li, Ningning Wang, Sihuang Hu +1
The sub-packetization and the field size are of paramount importance in the MSR array code constructions. For optimal-access MSR codes, Balaji et al. proved that $\ell\g…
ABS+ Polar Codes: Exploiting More Linear Transforms on Adjacent Bits
Guodong Li, Min Ye, Sihuang Hu
ABS polar codes were recently proposed to speed up polarization by swapping certain pairs of adjacent bits after each layer of polar transform. In this paper, we observe that apply…
Constructing MSR codes with subpacketization for helper nodes
Ningning Wang, Guodong Li, Sihuang Hu +1
Wang et al. (IEEE Transactions on Information Theory, vol. 62, no. 8, 2016) proposed an explicit construction of an Minimum Storage Regenerating (MSR) code with par…
All the codeword symbols in polar codes have the same SER under the SC decoder
Guodong Li, Min Ye, Sihuang Hu
We consider polar codes constructed from the kernel over a finite field , where is a power of a pr…
Adjacent-Bits-Swapped Polar codes: A new code construction to speed up polarization
Guodong Li, Min Ye, Sihuang Hu
The construction of polar codes with code length involves layers of polar transforms. In this paper, we observe that after each layer of polar transforms, one can swap…
A Dynamic Programming Method to Construct Polar Codes with Improved Performance
Guodong Li, Min Ye, Sihuang Hu
In the standard polar code construction, the message vector is divided into information bits and frozen bits according to the reliability of each gi…
