Low-Density Parity-Check (LDPC) codes are a type of error-correcting code that allows for efficient communication over noisy channels. They are characterized by their sparse parity-check matrices, which lead to a simple structure that enables effective decoding algorithms. LDPC codes are particularly significant in modern coding techniques, known for their performance close to the Shannon limit, and play a crucial role in various applications, including digital communications and data storage.
