Abstract
In this paper, a dynamic normalization technique is proposed to approximate the nonlinear operation in decoding LDPC codes. The criterion in determining the normalization factor is also presented with theoretical analysis. The proposed method improves the approximation accuracy as well as the error performance of min-sum algorithm. Furthermore, the hardware implementation benefits from a simplified normalization scheme, leading to reductions in complexity and implementation loss.
