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。 How to recognize the channel error correction code parameters based on the received data is still a difficult problem to be solved under unknown circumstances. According to the nature of linear block codes, a new data matrix model is proposed for blind identification of linear block codes. The method is generalized and applied to the blind identification of system convolutional codes, and achieved good results.
