Minimal Trellis Modules and Equivalent Convolutional Codes

open access: yesIEEE Transactions on Information Theory, 2006
In this correspondence, it is shown that some convolutional codes with distinct memory sizes of minimal encoders are equivalent in the sense that the minimal trellises of these codes are the shifted versions of one another.

Group Code Equivalence and Optimum Codes

IRE Transactions on Circuit Theory, 1959
This paper describes a search for optimum group codes using the IBM 704 computer. Some theory of the relation. ship between equivalent codes used in narrowing the search is described, and the method of searching is outlined. The newly found optimum codes are listed, along with a number of counter-examples to typical conjectures on binary group codes.

Equivalence of chain codes

Journal of Electronic Imaging, 2014
The representation of images is an active and very important area in image processing and pattern recognition. Therefore, in the literature, different contour codes for binary images have been proposed, such as F4;F8;VCC;3OT, and AF8. These codes have been used in many papers since the first chain code, F8, was introduced by Freeman in 1961.

On the equivalence of linear codes

Applicable Algebra in Engineering, Communication and Computing, 2011
The authors consider the problem of equivalence of linear codes, i.e., when they differ by a linear isometry of the Hamming space. In that case, the linear isometry is exactly a monomial transformation. Certain equivalent conditions are derived for this notion of equivalence, based upon properties of the relative codes obtained from the relative ...
