Claim 4:
5. The method according to claim 4, wherein the left-to-right message in the first table is calculated as follows:

Ri+1,j0=f(Ri,j2,Ri,j3),

Ri+1,j1=Ri,j3,

f(a,b)=sign(a*b)*min(|a|,|b|),, where Ri+1,j0 represents the left-to-right message associated with the right-upper node of the processing element, Ri+1,j1 represents the left-to-right message associated with the right-lower node of the processing element, Ri,j2 represents the left-to-right message associated with the left-upper node of the processing element, and Ri,j3 represents the left-to-right message associated with the left-lower node of the processing element, and
wherein the left-to-right messages associated with the most-left nodes are set based on bit positions of information bits and frozen bits in a source bit sequence from which the received information is originated, wherein the left-to-right message associated with the most-left node indicating the information bit is set to a first value and the left-to-right message associated with the most-left node indicating the frozen bit is set to a second value.
