DESCRIPTION:We describe the split-LDPC codes for channel coding of non-uni
 form sources.\nFirstly\, we give their encoding structure and illustrate t
 heir performance at finite length.\nThen\, we study the stability conditio
 n of split-LDPC under iterative decoding and\nthe evolution of message den
 sities on the graph representation. We also propose\na description of spli
 t-LDPC decoding as a bi-dimensional dynamic system associated\nto a very a
 ccurate Gaussian approximation of message densities.
