Low-density parity check (LDPC) codes are a type of error-correcting code that uses sparse parity-check matrices for improved error correction performance. Introduced by Robert Gallager in 1962, LDPC codes gained popularity due to their capacity-approaching performance and low decoding complexity. LDPC codes are widely used in practical applications such as telecommunications, data storage, and space missions. Prominent institutions like MIT, Stanford, and Berkeley have played significant roles in LDPC code research and development. Companies like Qualcomm have contributed to their commercialization, while IEEE sets standards for their adoption. Research on LDPC codes is published in leading academic journals like IEEE Transactions on Communications and IEEE Transactions on Information Theory.
