Abstract

In this paper, an Unequally Weighted Sliding-Window Belief Propagation (UW-SWBP) algorithm was proposed to decode the binary LDPC code. We model the important of overall beliefs of variable nodes in a sliding window as Gaussian distribution, which means central nodes play a more importance role than the nodes on both sides. The UW-SWBP demonstrates better performance than SWBP algorithm in both BER and FER metrics.

Keywords: UW-SWBP LDPC Overall belief
