摘要
在未知情况下如何仅仅根据接收的数据识别出信道纠错码的参数,目前还是个很难解决的问题。文章根据线性分组码的性质提出了一种新型数据矩阵模型,用于对线性分组码进行盲识别,并将该方法推广应用到系统卷积码盲识别,取得了很好的效果。
In unknown circumstances, how to identify the parameters of channel error-correcting code only according to the received data, is still a very difficult problem. Based on the nature of＇the linear block code, this paper propose a new data matrix model for the blind identification of linear block code, and the method is popularized and applied to the blind identification of system convolutional codes, a very good result is thus obtained.
