LDPC (Low-Density Parity-Check) codes

Low-Density Parity-Check (LDPC) codes are a type of error-correcting code used in digital communications to detect and fix errors caused by noise during transmission. They are characterized by a sparse matrix of bits that define relationships between data and parity bits. These codes enable efficient and reliable data transmission, especially in high-speed and high-noise environments like satellite or internet data. LDPC codes are powerful because their structure allows for strong error correction with less added redundancy, making data transmission more accurate and efficient without significantly reducing bandwidth.
