网络编码中的字段大小与成功概率

On Field Size and Success Probability in Network Coding

Olav Geil, Ryutaroh Matsumoto, Casper Thomsen

摘要:

利用代数几何和Groebner基理论的工具,我们解决了网络编码中的两个问题。首先,我们提出了一种方法来确定线性网络编码是可行的最小字段大小。其次,我们得到改进的估计的成功概率的随机线性网络编码。这些估计考虑到哪些单项式出现在埃德蒙兹矩阵的乘积的行列式的支持。因此,我们最后研究哪些单项式可以出现在埃德蒙兹矩阵的行列式。

英文摘要:

Using tools from algebraic geometry and Groebner basis theory we solve two problems in network coding. First we present a method to determine the smallest field size for which linear network coding is feasible. Second we derive improved estimates on the success probability of random linear network coding. These estimates take into account which monomials occur in the support of the determinant of the product of Edmonds matrices. Therefore we finally investigate which monomials can occur in the determinant of the Edmonds matrix.
