Abstract
Systems and methods are provided for decoding a codeword of a low density parity check (LDPC) code. The systems and methods may include receiving a vector corresponding to the codeword encoded with a parity check matrix, and processing a first portion of the received vector with a first portion of the parity check matrix to obtain a decoding estimate of a first portion of the codeword. The systems and methods may further include processing the decoding estimate of the first portion of the codeword with a second portion of the parity check matrix to obtain an intermediate vector, and processing a second portion of the received vector with a third portion of the parity check matrix and the intermediate vector to obtain a decoding estimate of a second portion of the codeword.
