摘要 该文提出了一种非规则LDPC码字基于度分布HARQ技术的改进方案。该方案在选择重传信息的过程中,不仅考虑了节点度分布的影响,而且考虑了非规则LDPC码字自身的不均等错误保护特性。与原始的基于度分布的HARQ方案相比,该方案使系统的误比特率和吞吐量指标得到了明显改善。 In this paper, a progressive HARQ scheme based on degree distribution for irregular LDPC codes is proposed. The proposed scheme considers Unequal Error Protection （UEP） of irregular LDPC codes as well as degree distribution while choosing some bits for retransmission. Compared with initial Degree Distribution Based HARQ （DDB-HARQ） scheme, this scheme improves system performance such as bit error rate and throughput.
