The paper is about bounds for LDPC and LDGM codes under MAP. A new method for analyzing low density parity check (LDPC) codes and low density generator matrix (LDGM) codes under bit maximum a posteriori probability (MAP) decoding is introduced. T

The Low-Density Parity-Check codes are among the most powerful forward error correcting codes, since they enable to get as close as a fraction of a dB the Shannon limit. This astonishing performance combined with their relatively simple decoding

The 5G new air standard describes the channel and frame structures of physical layer as a whole, including physical channels, ldpc and polar channel coding.
