On the Capacity of the Beta-Binomial Channel Model for Multi-Level Cell Flash Memories
Veeresh Taranalli, Hironori Uchikawa, Paul H. Siegel
The beta-binomial (BBM) channel model was recently proposed to model the overdispersed statistics of empirically observed bit errors in multi-level cell (MLC) flash memories. In th…
Channel Models for Multi-Level Cell Flash Memories Based on Empirical Error Analysis
Veeresh Taranalli, Hironori Uchikawa, Paul H. Siegel
We propose binary discrete parametric channel models for multi-level cell (MLC) flash memories that provide accurate ECC performance estimation by modeling the empirically observed…
Binary Linear Locally Repairable Codes
Pengfei Huang, Eitan Yaakobi, Hironori Uchikawa +1
Locally repairable codes (LRCs) are a class of codes designed for the local correction of erasures. They have received considerable attention in recent years due to their applicati…
Threshold Improvement of Low-Density Lattice Codes via Spatial Coupling
Hironori Uchikawa, Brian M. Kurkoski, Kenta Kasai +1
Spatially-coupled low-density lattice codes (LDLC) are constructed using protographs. Using Monte Carlo density evolution using single-Gaussian messages, we observe that the thresh…
Design and Performance of Rate-compatible Non-Binary LDPC Convolutional Codes
Hironori Uchikawa, Kenta Kasai, Kohichi Sakaniwa
In this paper, we present a construction method of non-binary low-density parity-check (LDPC) convolutional codes. Our construction method is an extension of Felstroem and Zigangir…
