A New Method for Building Low-Density-Parity-Check Codes

This paper proposes a new method for building low-density-parity-check codes, exempt of cycle of length 4, based on a circulant permutation matrix, which needs very little memory for storage it in the encoder and a dual diagonal apac1/60/1/cw structure is applied to guarantee that parity check bits can be recursively computed with linear calculatio
