摘　　要：如何构造高性能的LDPC码是LDPC研究领域的关键技术。本文利用改进的PEG算法构造出多元LDPC码,使其既能保持码字的性能,又能降低编码复杂度。实验结果表明PEG编码的LDPC码的性能明显优于随机编码的码字,并且改进的PEG算法能大大降低编码复杂度,使其更加实用。How to construct high-performance LDPC code is a key technology in LDPC research field. In this paper, the improved PEG algorithm is used to construct the multivariate LDPC code, which can not only maintain the performance of code word, but also reduce the coding complexity. The experimental results show that the performance of the LDPC code of PEG encoding is better than that of random code words, and the improved PEG algorithm can greatly reduce the coding complexity and make it more practical.
