Low-density parity-check codes

Low-Density Parity-Check (LDPC) codes are a type of error-correcting code used in digital communications. They add redundancy to transmitted data, enabling the receiver to detect and correct errors caused by noise or interference. LDPC codes are characterized by a sparse (mostly zeros) matrix that defines how data and check bits relate, which allows efficient and reliable decoding. This makes them highly effective for high-speed data transmission, such as in satellite communication, Wi-Fi, and 5G networks, ensuring your information arrives accurately even in challenging conditions.
