Figure 6From: Distributed joint source-channel code design for GMAC using irregular LDPC codesMutual information update through SCF nodes. I s → v ( 1 ) (output mutual information) as a function of I v → s ( 2 ) (input mutual information) for μ v → s ( 2 ) = 1.8 and α = 0.01. The corresponding message histogram is shown in Figure5.Back to article page
