随机网络编码中的部分扩频

Partial Spreads in Random Network Coding

Elisa Gorla, Alberto Ravagnani

摘要:

根据R. Kötter和F. R. Kschischang,我们研究网络码作为一族的k维线性子空间的向量空间F_q^n,q是一个素数幂和F_q有限域的q个元素。特别是,在有限射影几何的思想,我们引入了一类网络码,我们称之为“部分扩展码”。部分扩展码自然地推广了扩展码。在本文中,我们提供了一个简单的描述,这样的代码在矩阵,讨论其极大性,并提供了一个有效的解码算法。

英文摘要:

Following the approach by R. Kötter and F. R. Kschischang, we study network codes as families of k-dimensional linear subspaces of a vector space F_q^n, q being a prime power and F_q the finite field with q elements. In particular, following an idea in finite projective geometry, we introduce a class of network codes which we call "partial spread codes". Partial spread codes naturally generalize spread codes. In this paper we provide an easy description of such codes in terms of matrices, discuss their maximality, and provide an efficient decoding algorithm.
