Reliability-based syndrome decoding of LDPC codes

Aiming at bridge gap between maximum likelihood decoding (M LD) and belief propagation (BP) decoding for short or medium LDPC codes, we present one modifi ed ordered statistics decoding (OSD) reprocessing method, which is serially concatenated with s tandard BP. Meanwhile, two novel points in implementation are addressed. For one thing, the new definit ion… (More)
