Capacity Achieving LDPC Codes Through Puncturing
The performance of punctured LDPC codes under maximum-likelihood (ML) decoding is studied in this paper via deriving and analyzing their average weight distributions (AWDs) and th...

Maxwell Construction: The Hidden Bridge Between Iterative and Maximum a Posteriori Decoding
There is a fundamental relationship between belief propagation and maximum a posteriori decoding. A decoding algorithm, which we call the Maxwell decoder, is introduced and provide...

State Discrimination With Post-Measurement Information
We introduce a new state discrimination problem in which we are given additional information about the state after the measurement, or more generally, after a quantum memory bound ...

Discrete-Input Two-Dimensional Gaussian Channels With Memory: Estimation and Information Rates Via Graphical Models and Statisti
Abstract--Discrete-input two-dimensional (2-D) Gaussian channels with memory represent an important class of systems, which appears extensively in communications and storage. In sp...

A Note on Rate-Distortion Functions for Nonstationary Gaussian Autoregressive Processes
Source coding theorems and Shannon rate-distortion functions were studied for the discrete-time Wiener process by Berger and generalized to nonstationary Gaussian autoregressive p...

Universal Lossless Compression of Erased Symbols
A source XXX goes through an erasure channel whose output is ZZZ. The goal is to compress losslessly XXX when the compressor knows XXX and ZZZ and the decompressor knows ZZZ. We pr...

Locally Optimum Detection of Signals in Multiplicative and First-Order Markov Additive Noises
Abstract--In most previously reported studies on locally optimum detection of signals, independent observations have been assumed in various noise environments. The use of an indep...
