“…Therefore, the position of connection degree of the variable node is an important parameter. Recently, this property has been exploited in [4]. Since the optimization of the LDPC codes is done by minimizing the probability of error, the optimized code does not have good performance in term of FER below the targeting probability of error.…”

“…In a real system, SNRs are different between the subcarriers (or equivalently for every variable node) and therefore the means m u0,i (h i ) are different for each i as well. In order to drastically reduce the number of parameters m u0,i , we use the same approximation that is proposed in [4]. The original channel spectrum shown on Fig.…”
