  In this paper, we give a distributed joint source channel coding scheme for
arbitrary correlated sources for arbitrary point in the Slepian-Wolf rate
region, and arbitrary link capacities using LDPC codes. We consider the
Slepian-Wolf setting of two sources and one destination, with one of the
sources derived from the other source by some correlation model known at the
decoder. Distributed encoding and separate decoding is used for the two
sources. We also give a distributed source coding scheme when the source
correlation has memory to achieve any point in the Slepian-Wolf rate achievable
region. In this setting, we perform separate encoding but joint decoding.
