Abstract

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.
