Abstract: One controls the number of iterations of a process of iterative decoding of a symbol sequence coded according to a coding scheme using concatenation of convolutional codes in cases of non-convergence. One firstly calculates a quantity related to the convergence of the iterative decoding process, then one compares this quantity with a non-convergence threshold. As a function of this comparison, the iterative decoding process is halted while declaring the sequence undecoded.

Abstract translation: 一个控制在不收敛的情况下，使用卷积码串联，根据编码方案编码的符号序列的迭代解码过程的迭代次数。 首先计算与迭代解码处理的收敛相关的数量，然后将该数量与非收敛阈值进行比较。 作为该比较的函数，迭代解码过程在声明序列未解码的同时停止。
