Histogram-Based Flash Channel Estimation
Haobo Wang, Tsung-Yi Chen, Richard D. Wesel
Current generation Flash devices experience significant read-channel degradation from damage to the oxide layer during program and erase operations. Information about the read-chan…
Variable-length Convolutional Coding for Short Blocklengths with Decision Feedback
Adam R. Williamson, Tsung-Yi Chen, Richard D. Wesel
This paper presents a variable-length decision-feedback scheme that uses tail-biting convolutional codes and the tail-biting Reliability-Output Viterbi Algoritm (ROVA). Comparing w…
Many-Broadcast Channels: Definition and Capacity in the Degraded Case
Tsung-Yi Chen, Xu Chen, Dongning Guo
Classical multiuser information theory studies the fundamental limits of models with a fixed (often small) number of users as the coding blocklength goes to infinity. Motivated by…
Increasing Flash Memory Lifetime by Dynamic Voltage Allocation for Constant Mutual Information
Tsung-Yi Chen, Adam R. Williamson, Richard D. Wesel
The read channel in Flash memory systems degrades over time because the Fowler-Nordheim tunneling used to apply charge to the floating gate eventually compromises the integrity of…
Protograph-Based Raptor-Like LDPC Codes
Tsung-Yi Chen, Kasra Vakilinia, Dariush Divsalar +1
This paper proposes a class of rate-compatible LDPC codes, called protograph-based Raptor-like (PBRL) codes. The construction is focused on binary codes for BI-AWGN channels. As wi…
