Abstract: An improved LDPC encoding and encoding and associated architectures therefor are described. In one exemplary embodiment, a set of parity bits (p) are generated from a set of information bits (s), by storing information related to z×z sub-matrices of a first sub-matrix and of a second sub-matrix corresponding to a first and a second portion of a parity check matrix H of an LDPC code, to allow representation of the parity check matrix in a compressed form and by generating the set of parity bits p by appropriately multiplying, shifting and accumulating subsets from the set of information bits s based on the stored information, without decompressing the parity check matrix. Further relevant techniques are also described.
