Quantizing for Noisy Flash Memory Channels
Juyun Oh, Taewoo Park, Jiwoong Im +2
Flash memory-based processing-in-memory (flash-based PIM) offers high storage capacity and computational efficiency but faces significant reliability challenges due to noise in hig…
Design of Bilayer and Multi-layer LDPC Ensembles from Individual Degree Distributions
Eshed Ram, Yuval Cassuto
A new approach for designing bilayer and multi-layer LDPC codes is proposed and studied in the asymptotic regime. The ensembles are defined through individual uni-variate degree di…
On the Decoding Performance of Spatially Coupled LDPC Codes with Sub-block Access
Eshed Ram, Yuval Cassuto
We study spatially coupled LDPC codes that allow access to sub-blocks much smaller than the full code block. Sub-block access is realized by a semi-global decoder that decodes a ch…
Spatially Coupled Codes with Sub-Block Locality: Joint Finite Length-Asymptotic Design Approach
Homa Esfahanizadeh, Eshed Ram, Yuval Cassuto +1
SC-LDPC codes with sub-block locality can be decoded locally at the level of sub-blocks that are much smaller than the full code block, thus providing fast access to the coded info…
Treeplication: An Erasure Code for Distributed Full Recovery under the Random Multiset Channel
Michael Gandelman, Yuval Cassuto
This paper presents a new erasure code called Treeplication designed for distributed recovery of the full information word, while most prior work in coding for distributed storage…
Efficient Compression of Long Arbitrary Sequences with No Reference at the Encoder
Yuval Cassuto, Jacob Ziv
In a distributed information application an encoder compresses an arbitrary vector while a similar reference vector is available to the decoder as side information. For the Hamming…
