Universal Parallel Concatenated Turbo Codes with Customizable Component Code Polynomials

This source code package references Professor Robert G. Maunder's 2008 open-source EXIT charts demo from the University of Southampton, providing plotting source code for universal parallel concatenated Turbo codes with customizable component code polynomials. The implementation features MATLAB-based algorithms for generating EXIT charts with configurable polynomial parameters through systematic encoding functions. The codebase supports iterative trajectory visualization using Monte Carlo simulation methods and BER contour mapping with SNR scaling algorithms. For computationally intensive scenarios involving large block lengths, the package includes pre-simulated results for common polynomial configurations (accessible via data loading functions) that enable immediate plotting without rerunning simulations. Additionally, the package incorporates S.Ten Brink's seminal reference on EXIT chart fundamentals and the author's technical review analyzing iterative decoding techniques in communication systems, including convergence analysis and threshold optimization approaches.
