网络编码的编码构造

Construction of Codes for Network Coding

Andreas-Stephan Elsenhans, Axel Kohnert, Alfred Wassermann

摘要:

基于Kötter和Kschischang的思想,我们使用常维子空间作为网络中的码字。我们显示了一个连接到理论的q-类似物的组合设计,这已被研究在布劳恩,克尔伯和劳厄作为一个纯粹的组合对象。对于网络代码的建设,我们成功地修改了方法(建设规定的自同构)最初开发的q-类似物的组合设计。然后,我们给出了一个特殊的情况下,该方法允许建设一个非常大的环境空间的网络代码,我们还展示了如何解码这样的代码与一个非常少的操作。

英文摘要:

Based on ideas of Kötter and Kschischang we use constant dimension subspaces as codewords in a network. We show a connection to the theory of q-analogues of a combinatorial designs, which has been studied in Braun, Kerber and Laue as a purely combinatorial object. For the construction of network codes we successfully modified methods (construction with prescribed automorphisms) originally developed for the q-analogues of a combinatorial designs. We then give a special case of that method which allows the construction of network codes with a very large ambient space and we also show how to decode such codes with a very small number of operations.
