文中研究了一维串行校验-卷积级联码(1D SPCCC)及其译码的迭代维特比算法(IVA),提出了改进的IVA,并做了大量的仿真实验,结果表明这种改进的IVA能够在基本不增加计算量和不降低收敛速度的基础上,使1D SPCCC的译码性能得到较为明显的改善。
In this paper, one-dimensional serial parity-convolutional concatenation code (1D SPCCC) and its iterative Viterbi algorithm (IVA) are studied. An improved IVA is proposed and a large number of simulation experiments are carried out. The results show that this The improved IVA can significantly improve the decoding performance of 1D SPCCC without increasing the amount of computation and without reducing the convergence rate.
