MATLAB simulation program for QC-LDPC channel coding, featuring matrix G generation, cycle-4 detection, and analysis capabilities
Detailed Documentation
QC-LDPC channel coding is a widely used encoding technique that enhances data transmission reliability. Our MATLAB simulation provides comprehensive functionality including generation of the parity-check matrix G through structured construction algorithms based on quasi-cyclic properties. The program implements efficient cycle detection algorithms to identify the presence of length-4 cycles, which is crucial for optimizing code performance and avoiding error floor phenomena. Key functions include matrix initialization using circulant permutation matrices, belief propagation decoding implementation, and cycle analysis tools for code optimization. These features enable deeper analysis and refinement of QC-LDPC codes, helping users better understand and apply this channel coding technology. Welcome to explore our simulation program!
