  • Abstract
    This paper considers the LDPC-based Slepian-Wolf coding with decoder side information. The paper analyzes the statistical properties of LDPC syndromes and shows that there are residual redundancies in LDPC syndromes, especially at low rates. Furthermore, this paper proposes a rate-adaptive way to compress LDPC syndromes.
