LDGM Codes for Channel Coding and Joint Source-Channel Coding of Correlated Sources

LDGM Codes for Channel Coding and Joint Source-Channel Coding of Correlated Sources

We propose a coding scheme based on the use of systematic linear codes with low-density generator matrix (LDGM codes) for channel coding and joint source-channel coding of multiterminal correlated binary sources. In both cases, the structures of the LDGM encoder and decoder are shown, and a concaten...
