MATLAB Simulation Programs for Low-Density Parity-Check (LDPC) Codes

I am delighted to share these MATLAB simulation programs for Low-Density Parity-Check (LDPC) codes with the community. These programs are designed to help you gain a deeper understanding of LDPC code concepts, practical implementation, and real-world applications. Through these simulations, you can actively construct LDPC codes from scratch and perform comprehensive performance analysis using built-in BER (Bit Error Rate) and FER (Frame Error Rate) evaluation modules. The code includes implementations of key algorithms such as iterative belief propagation decoding, parity-check matrix generation, and Tanner graph visualization. Additionally, the programs provide reference materials that explain the underlying principles and advantages of LDPC codes, including comparisons with other error-correcting codes and optimization techniques. I hope these resources prove valuable for your learning and research endeavors in channel coding theory! Key implementation features covered: - Structured parity-check matrix construction using algebraic methods - Log-domain sum-product algorithm for efficient decoding - Simulation frameworks for AWGN and fading channels - Performance plotting functions for iterative decoding convergence analysis
