Técnica de decodificação híbrida iterativa para códigos LDPC

A hybrid decoding system for LDPC codes em- ploying min-sum belief propagation (BP) decoding to correct errors, combined with erasure iterative decoding, is investigated by means of computer simulation. The proposed hybrid decoding system by employing a reduced number of iterations becomes more efficient, especially in the error-floor region, achieving a similar performance with equivalent implementation complexity to that of min-sum BP decoding schemes
