线性网络编码的类型保持转换矩阵
Type-preserving conversion matrix for linear network codes
摘要
Abstract
The concept of type-preserving conversion matrix is proposed to describe the conversion relationship between two linear network codes of the same type but of different rates. Its existence is proved for all four types of linear network codes. Then, a unified framework for the constructions of all four types of variable-rate linear network codes is proposed. Toimplement variable-rate network codes of any type constructed by this framework, every non-source node in the network needs to store only one local encoding kernel. When the transmission rate varies,only the source node needs to change it local encoding kernel with corresponding type-preserving conversion matrix, while the network-coding operations performed at every non-source node remain unchanged.关键词
