摘要
在智能通信以及电子对抗领域,信道编码盲识别发挥着重要作用。相比于传统Turbo码,双二元Turbo码具有更高的编码效率,因此被广泛使用。针对双二元Turbo码盲识别问题,提出一种编码参数全盲识别方法。该方法对子编码器结构进行深入分析和分解,进而建立分层次识别模型,恢复交织后序列,利用符号匹配方法确定交织关系,完成码字参数全盲识别。通过比对识别参数与预先设定参数,验证该方法具有正确性和有效性。
Blind recognition of channel coding plays an important role in the field of intelligence communication and information countermeasure. Compared to the traditional Turbo code, double-binary Turbo code has higher coding efficiency, so it is widely used.A blind recognition method for the doublebinary turbo coding parameter are proposed for the first time. Based on the analysis of sub-encoder structure and then decomposed it into two parts to establish the hierarchical recognition model. Then recoverying the interleaver sequence of turbo codes by the model, interleaver mapping is dicided by use the symbol matching method. The reliablity of the method are verified by comparing the recognized parameters and pre-set parameters.
