Dictator Functions Maximize Mutual Information
Georg Pichler, Pablo Piantanida, Gerald Matz
Let denote independent, identically distributed copies of two arbitrarily correlated Rademacher random variables . We prove that the inequality…
Distributed Information-Theoretic Clustering
Georg Pichler, Pablo Piantanida, Gerald Matz
We study a novel multi-terminal source coding setup motivated by the biclustering problem. Two separate encoders observe two i.i.d. sequences and , respectively. The goa…
Quantized Message Passing for LDPC Codes
Michael Meidlinger, Alexios Balatsoukas-Stimming, Andreas Burg +1
We propose a quantized decoding algorithm for low- density parity-check codes where the variable node update rule of the standard min-sum algorithm is replaced with a look-up table…
An Approach to Complex Bayesian-optimal Approximate Message Passing
Gabor Hannak, Martin Mayer, Gerald Matz +1
In this work we aim to solve the compressed sensing problem for the case of a complex unknown vector by utilizing the Bayesian-optimal structured signal approximate message passing…
A Fully-Unrolled LDPC Decoder Based on Quantized Message Passing
Alexios Balatsoukas-Stimming, Michael Meidlinger, Reza Ghanaatian +2
In this paper, we propose a finite alphabet message passing algorithm for LDPC codes that replaces the standard min-sum variable node update rule by a mapping based on generic look…
Spatially-Coupled LDPC Codes for Decode-and-Forward Relaying of Two Correlated Sources over the BEC
Stefan Schwandter, Alexandre Graell i Amat, Gerald Matz
We present a decode-and-forward transmission scheme based on spatially-coupled low-density parity-check (SC-LDPC) codes for a network consisting of two (possibly correlated) source…
