LDPC MATLAB Toolbox

This LDPC MATLAB toolbox offers an extended framework with additional implementation details. LDPC (Low-Density Parity-Check) represents a powerful channel coding technique widely adopted in modern communication systems for error correction. The MATLAB environment provides an ideal platform for developing and testing LDPC algorithms through its extensive mathematical computing capabilities. This specialized toolbox includes complete implementations of both LDPC encoding and decoding processes, featuring key algorithms such as belief propagation (sum-product algorithm) for iterative decoding. The package contains modular functions for generator matrix creation, parity check matrix generation, and various decoding methodologies including log-domain implementations for improved numerical stability. These programs enable efficient data encoding and decoding operations, significantly enhancing communication system reliability and performance through optimized bit-error-rate (BER) characteristics. The toolbox also includes simulation examples demonstrating performance under different channel conditions and code parameters.
