ON NEW MATHEMATIC MODEL OF DISPERSE CONVOLUTIONAL CODER-DECODER

介绍一种易于软件实现的新型离散卷积编译码器的数学模型,通过修改生成矩阵的表述方法来完成一个普通的卷积码编译过程,并给出该算法的流程。这种数学模型与传统数学模型相比,时间复杂度低,且易于软件实现。

In this paper it presented a new mathematic model of disperse convolutional coder-decoder which is easy to implement in software. It is easy to accomplish the compiling process of all ordinary convolutional code by modifying the expressing way of generated matrix. The paper also presented the flow implemented by this algorithm. Compared with traditional mathematic expression of generator matrix, the new algorithm has lower complexity and easier to implement in software.
