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…
Optimizing Pilot Length for a Go/No-Go Decision in Two-State Block Fading Channels with Feedback
Chung-Yu Lou, Babak Daneshrad, Richard D. Wesel
We propose an approach where each user independently seeks to minimize the amount of time that they occupy the channel. Essentially, we seek to minimize the number of transmitted s…
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…
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…
