Simulation program for MAX-Log-MAP decoding algorithm of Turbo codes, developed based on Dr. Wu Yufei's Turbo code MATLAB simulation framework. While Dr. Wu's original program must be downloaded separately, this subroutine can be directly integrated as a replacement component and utilizes Wu's auxiliary functions. The implementation features simplified logarithmic computations for reduced complexity while maintaining near-optimal performance through approximation techniques in the forward-backward recursion algorithm.

This source code package is based on Professor Robert G. Maunder's 2008 EXIT charts open-source demo from the University of Southampton. It provides plotting source code for generating EXIT charts of universal parallel concatenated Turbo codes with customizable component code polynomials. The implementation supports iterative trajectory plotting, BER contour mapping, and additional visualization tasks. For simulations involving large block lengths requiring extended processing time, the package includes pre-computed simulation results for selected component code polynomials that can be directly used for plotting. The package also contains S.Ten Brink's foundational reference on EXIT chart principles and the author's review paper analyzing iterative decoding processes in communication systems.
