Density Evolution for the Design of Non-Binary Low Density Parity Check Codes for Slepian-Wolf Coding

In this paper, we investigate the problem of designing good non-binary LDPC codes for Slepian-Wolf coding. The design method is based on Density Evolution which gives the asymptotic error probability of the decoder for given code degree distributions. Density Evolution was originally introduced for...
