Resource Overview
This MATLAB implementation features a channel codec compliant with China's DTTB standard, utilizing LLR-BP decoding algorithm with configurable iteration parameters. The program includes modular functions for encoding/decoding operations and will be supplemented with standard-compliant generator and parity-check matrices.
Detailed Documentation
I have developed a MATLAB program implementing a channel codec following China's Digital Television Terrestrial Broadcasting standard. The core decoding component employs the Log-Likelihood Ratio Belief Propagation (LLR-BP) algorithm, which iteratively updates probability messages across Tanner graph nodes for improved error correction performance. The implementation includes parameterized functions for codeword generation, parity checking, and iterative decoding cycles with configurable maximum iterations and convergence thresholds.
I welcome feedback and suggestions for optimization regarding algorithm efficiency and code structure. Additionally, I will subsequently upload the standard-compliant generator matrix (for systematic encoding) and parity-check matrix (for syndrome calculation) that adhere to the national specification. Let's collaborate to enhance this implementation through performance benchmarking and code refinement!
