MATLAB Implementation of LDPC Decoding Algorithm

In this document, I will demonstrate how to implement the LDPC decoding algorithm using MATLAB. The LDPC code features a 960-bit codeword length and 1/2 code rate, with complete hardware simulation matching FPGA implementation requirements and integrated quantization processing. LDPC coding is a powerful and efficient error correction technique that can detect and correct data errors during transmission. To implement this algorithm, we will utilize MATLAB's built-in functions and tools along with appropriate programming approaches. The implementation involves key steps including: - Quantization scheme design for fixed-point arithmetic compatibility - Parity check matrix construction matching the specified code parameters - Iterative decoding using belief propagation or min-sum algorithms - Hardware-friendly memory management and parallel processing simulation Through detailed explanations of the LDPC decoding algorithm and step-by-step implementation procedures, this guide aims to help you better understand and apply LDPC coding technology in practical hardware-oriented applications. The code includes specific considerations for FPGA implementation such as resource optimization and timing constraints.
