论文摘要
在这封信中,我们提出了一个在二元擦除通道(BEC)上的非二元低密度平价检查(LDPC)代码的混合迭代解码器,该代码基于该代码,该代码基于擦除概率的递归递归,以设计非二进制LDPC代码,具有反合式优化程度分布。由此产生的一步解码树是无循环的,并且可以达到较低的解码复杂性。实验研究表明,提出的收敛性优化算法将收敛过程加速33%。
In this letter, we present a hybrid iterative decoder for non-binary low density parity check (LDPC) codes over binary erasure channel (BEC), based on which the recursion of the erasure probability is derived to design non-binary LDPC codes with convergence-optimized degree distributions. The resulting one-step decoding tree is cycle-free and achieves lower decoding complexity. Experimental studies show that the proposed convergence-optimization algorithm accelerates the convergence process by 33%.
