Abstract
A system based on the use of systematic linear codes with low-density generator matrix (LDGM codes) for joint source-channel coding of multiterminal correlated binary sources is proposed. The encoding structure and different decoding possibilities are investigated and evaluated. For the case of binary sources and AWGN channels, the resulting performance is close to the theoretical limits.
