Quantized Iterative Message Passing Decoders with Low Error Floor for LDPC Codes
Xiaojie Zhang, Paul H. Siegel
The error floor phenomenon observed with LDPC codes and their graph-based, iterative, message-passing (MP) decoders is commonly attributed to the existence of error-prone substruct…
Rewriting Codes for Flash Memories
Eitan Yaakobi, Hessam Mahdavifar, Paul H. Siegel +2
Flash memory is a non-volatile computer memory comprising blocks of cells, wherein each cell can take on q different values or levels. While increasing the cell level is easy, redu…
Numerical Issues Affecting LDPC Error Floors
Brian K. Butler, Paul H. Siegel
Numerical issues related to the occurrence of error floors in floating-point simulations of belief propagation (BP) decoders are examined. Careful processing of messages correspond…
Time-Space Constrained Codes for Phase-Change Memories
Minghai Qin, Eitan Yaakobi, Paul H. Siegel
Phase-change memory (PCM) is a promising non-volatile solid-state memory technology. A PCM cell stores data by using its amorphous and crystalline states. The cell changes between…
Error Floor Approximation for LDPC Codes in the AWGN Channel
Brian K. Butler, Paul H. Siegel
This paper addresses the prediction of error floors of low-density parity-check (LDPC) codes with variable nodes of constant degree in the additive white Gaussian noise (AWGN) chan…
Bounds on the Minimum Distance of Punctured Quasi-Cyclic LDPC Codes
Brian K. Butler, Paul H. Siegel
Recent work by Divsalar et al. has shown that properly designed protograph-based low-density parity-check (LDPC) codes typically have minimum (Hamming) distance linearly increasing…
