On the Capacity of Channels with Timing Synchronization Errors
Aravind R. Iyengar, Paul H. Siegel, Jack K. Wolf
We consider a new formulation of a class of synchronization error channels and derive analytical bounds and numerical estimates for the capacity of these channels. For the binary c…
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…
Windowed Decoding of Spatially Coupled Codes
Aravind R. Iyengar, Paul H. Siegel, Rudiger L. Urbanke +1
Spatially coupled codes have been of interest recently owing to their superior performance over memoryless binary-input channels. The performance is good both asymptotically, since…
Modeling and Information Rates for Synchronization Error Channels
Aravind R. Iyengar, Paul H. Siegel, Jack K. Wolf
We propose a new channel model for channels with synchronization errors. Using this model, we give simple, non-trivial and, in some cases, tight lower bounds on the capacity for ce…
Write Channel Model for Bit-Patterned Media Recording
Aravind R. Iyengar, Paul H. Siegel, Jack K. Wolf
We propose a new write channel model for bit-patterned media recording that reflects the data dependence of write synchronization errors. It is shown that this model accommodates b…
Windowed Decoding of Protograph-based LDPC Convolutional Codes over Erasure Channels
Aravind Iyengar, Marco Papaleo, Paul Siegel +3
We consider a windowed decoding scheme for LDPC convolutional codes that is based on the belief-propagation (BP) algorithm. We discuss the advantages of this decoding scheme and id…
