    • The method is for correcting and decoding a sequence of branches representing encoded data bits into estimated information bits. The encoded data bits were previously encoded in a convolutional manner with v encoded symbols forming a branch where v is a predetermined value. The method comprising the steps of (a) setting accumulation, correction and event indicators respectively into non-accumulating, non-active and incomplete states, and setting a precedent Nccb variable at a predetermined value N; (b) receiving the sequence of branches, for each of the branches received in the step (b) a series of verification and calculation being performed; and (c) verifying whether the branch corresponding to the oldest undelivered estimated information bit has gone through all the substeps of step (b), and if it is the case, delivering the oldest undelivered estimated information bit when the oldest undelivered estimated information bit is no longer convolutionally associated with any of the branches corresponding to the syndromes stored in the first and second registers. An apparatus for performing the method is also described.
    • 该方法用于将表示编码数据位的分支序列校正和解码为估计信息比特。 编码数据位先前以卷积方式编码,其中v个编码符号形成分支,其中v是预定值。 该方法包括以下步骤:(a)将累积,校正和事件指示分别设置为非累积,非有效和不完全状态,并将先前的Nccb变量设置为预定值N; (b)对步骤(b)中接收的每个分支接收一系列验证和计算; 和(c)验证与最旧的未传送估计信息位对应的分支是否已经经过步骤(b)的所有子步骤,如果是这样的话,当最旧的未传送估计信息位为 不再与存储在第一和第二寄存器中的综合征相对应的任何分支卷积关联。 还描述了一种用于执行该方法的装置。
