摘要 使用高斯近似和最优化理论的方法,对基于LDPC码度分布的混合自动重发请求(HARQ)方案的性能进行了研究。研究表明,根据LDPC编码的度分布和初始信道条件,能够确定一个编码码字中各个度数的比特所对应的最优的重发比例,如果按照该比例进行重发,重发功率的效率能够最大化。计算结果显示基于LDPC码度分布的混合自动重发请求方案具有最优的重发比例,是一种最优化方案。 By analyzing the degree distribution of low density parity check （LDPC） codes in definite quantity with gaussian approximation （GA） and optimal method, the performance of degree distribution for LDPC codes is investigated. Research results show that when the initial channel state and degree distribution of the LDPC codes are known, the optimal retransmission fractions can be determined. Maximum retransmission efficiency would be achieved if bits can be retransmitted according to these fractions. Calculation results reveal that the retransmission fractions in degree distribution based hybrid automatic repeat quest （DDB-HARQ） scheme are optimal.
