摘要 LDPC码的短回路极大地影响了其性能,用图的理论来描述LDPC码,从而可以给出所有的回路,以及回路所经过的节点和长度。这种算法非常适合计算机进行搜索。 Short loops are detrimental to the performance of LDPC codes, in this correspondence tree graph to depict LDPC code,is introduced and by this method the method of calculating all loops and their length is offerod. This Algorithm fits computer to search loops in LDPC codes.
