 Actually i am not getting about the type of decoder concerned with partially parallel or fully serial bcoz I have to implement the LDPC decoder with the help of belief propagation algorithm.In that process i have been provided with a H matrix,code word like [0 0 1 0 1 1] for a 4*6 matrix.The received word is r=[1 0 1 0 1 1] with a cross over probability of p=0.2. Now the steps which i have to follow for computation is as follows:- 1.in the first step using logp/1-p i have to find out the received word and it comes like r=[-1.3863,1.3863,-1.3863,1.3863,-1.3863,1.3863] 2.Since it is a 4*6 matrix M11=r1=-1.3863 and M31=r1=-1.3863 for i=2,M12=r2=1.3863 and M22=r2=1.3863 . . . . for i=6 M36=r6=-1.3863 and M46=r6=-1.3863 3.Extrensic information.It is calculated by using formula E11=log(1+tanh(M12/2)tanh(M14/2)/1-tanh(M12/2)tanh(M14/2)) Like that i have to calculate for eacha nd every node and finally a E matrix has been formed 4.calculation of LLR L1=r1+E11+E31=some value . . . . L6=some value finally on the basis of BPSK scheme Z=[0 0 1 0 1 1] 5.To check if Z is a valid codeword S=Z.H transpose if it comes like [0 0 0 0] then my code word is correct otherwise have to go for next iteration. Please tell me how should i proceed.Its a total mathematical calculation.I am stuck with the point of taking matrix as a input.If i take it as an array also then how should i calculate that tanh calculation.
