Characterizing flash memory: Anomalies, observations, and applications
TLDR
This paper empirically characterizes flash memory technology by measuring the performance, power, and reliability of flash devices from five manufacturers. Expand
Capacity-approaching bandwidth-efficient coded modulation schemes based on low-density parity-check codes
TLDR
We design multilevel coding (MLC) and bit-interleaved coded modulation (BICM) schemes based on low-density parity-check (LDPC) codes. Expand
Performance analysis and code optimization of low density parity-check codes on Rayleigh fading channels
TLDR
A numerical method has been presented to determine the noise thresholds of low density parity-check codes that employ the message passing decoding algorithm on the additive white Gaussian noise (AWGN) channel. Expand
Windowed Decoding of Protograph-Based LDPC Convolutional Codes Over Erasure Channels
TLDR
We show that the structure of LDPC convolutional code ensembles is suitable to obtain performance close to the theoretical limits over the memoryless erasure channel, both for the BP decoder and windowed decoding. Expand
Matched spectral-null codes for partial-response channels
TLDR
A new family of codes that improve the reliability of digital communication over noisy, partial-response channels is described. Expand

TLDR
We show that by starting from a simple LP problem and adaptively adding the necessary constraints, the complexity of LP decoding can be significantly reduced. Expand
Codes for Digital Recorders
TLDR
This paper surveys the theory and practice of constrained coding, tracing the evolution of the subject from its origins in Shannon's classic 1948 paper to present-day applications in high-density digital recorders. Expand
