Reed-Muller码的双向搜索译码
BIDIRECTIONAL SEARCH DECODING OF REED-MULLER CODES
-
摘要: 本文提出了Reed-Muller码的一种双向搜索算法,并证明了该算法实现了广义最小距离译码。其复杂度较Forney的译码算法降低很多,而其完备译码的性能经计算机模拟表明,与最大似然译码几乎一样。Abstract: A method which uses the bidirectional search to decode Reed-Muller codes is presented. It is proved to be a generalized minimum distance (GMD) algorithm. The complexity is much simpler than that of Forney s method. The computer simulation shows that the performance of this approach is almost the same as that of maximum likelihood decoding (MLD).
