Correlation Parameter Estimation for LDPC-Based Slepian-Wolf Coding

초록

Currently, many practical SWC systems are implemented using the low-density parity-check (LDPC) codes in which the virtual correlation channel between source and side information is modeled as a binary symmetric channel (BSC) characterized by the crossover probability. This paper is contributed to the estimation of crossover probability through the probability mass function (PMF) of the magnitudes of log-likelihood ratio (LLR) messages. Simulation. results are given to verify our proposed method.
