LDPC Codes, or Low-Density Parity-Check Codes, are a type of error-correcting code used in digital communications and data storage. They work by adding redundancy to the data being transmitted, allowing the receiver to detect and correct errors that may occur during transmission. This is particularly useful in noisy environments where data integrity is crucial. These codes are characterized by their sparse parity-check matrices, which means that most of the entries are zero. This sparsity allows for efficient decoding algorithms, making LDPC Codes suitable for high-performance applications, such as Wi-Fi, satellite communications, and data compression.
