lcrypto / protograph_exit_chart

Simple implementation (polynomial approx.) of Protograph EXIT-chart (PEXIT) for estimation of iterative decoding threshold of LDPC codes using Mutual Information

Protograph_EXIT_chart

The GitHub repository includes a simple MATLAB implementation of PEXIT charts for estimating the iterative decoding threshold of Low-Density Parity-Check (LDPC) codes based on mutual information. This implementation is based on the article "Protograph LDPC Codes Design Based on EXIT Analysis" by G. Liva and M. Chiani, published in the IEEE Global Telecommunications Conference in 2007.

The repository contains the necessary code to implement PEXIT charts and estimate the iterative decoding threshold of LDPC codes.
