Question: In LDPC code belief propagation, you said that transmitting ratio of P(xt=1|Ei)/P(xt=0|Ei) is sufficient since P(xt=0|Ei)+P(xt=1|Ei)=1. But since we are transmitting a message which is proportional to P(xt=*|Ei), k*[P(xt=0|Ei)+P(xt=1|Ei)]= 1; where k is proportionality constant. Is it correct?
