Here is a list of LDPC codes.
Code Description
Low-density parity-check (LDPC) code Also known as Gallager codes. Family of $$[n,k,d]$$ linear codes for which the number of nonzero entries in each row and column of the parity check matrix are both bounded by a constant as $$n\to\infty$$. In other words, the parity-check matrix of an LDPC code is sparse.
