Low-density parity-check code: History & Applications

Low-density parity-check (LDPC) codes, also known as Gallager codes, are a class of error-correction codes first proposed in 1960. Together with the closely related turbo codes, they have gained prominence in coding theory and information theory since the late 1990s. The codes today are widely used in applications ranging from wireless communications to…
