关于斜卷积码和格形码

On Skew Convolutional and Trellis Codes

Vladimir Sidorenko, Wenhui Li, Onur Günlü, Gerhard Kramer

摘要:

提出了有限域$\F$上的两类新的斜交码,称为斜卷积码和斜格码。这两个类分别由$\F$上的斜多项式的分数的斜域上的左或右子模定义。斜卷积码可以表示为周期性时变普通卷积码。斜格码在$\F$上一般是非线性的。这两类的每一个码都有一个码格,可以用维特比或BCJR算法解码。

英文摘要:

Two new classes of skew codes over a finite field $\F$ are proposed, called skew convolutional codes and skew trellis codes. These two classes are defined by, respectively, left or right sub-modules over the skew fields of fractions of skew polynomials over $\F$. The skew convolutional codes can be represented as periodic time-varying ordinary convolutional codes. The skew trellis codes are in general nonlinear over $\F$. Every code from both classes has a code trellis and can be decoded by Viterbi or BCJR algorithms.
