In this paper we introduce the construction of new families of error-correcting codes based on irregular low-density parity-check codes, which we called Generalized Irregular Low Density (GILD) codes, where as component codes, single-error correcting Hamming codes are used instead of single-error detecting parity-check codes. The decoding of GILD is based on simple and fast SISO (Soft Input -Soft Output) decoding of Hamming component codes. Simulation results over an AWGN channel indicate that excellent performances can be achieved.
