论文摘要
通过允许中间节点混合从多个来源收到的消息，网络编码是现代通信网络的新的新范式。计算策略是网络编码的一种类别，其中继电器将根据观察到的频道系数来解码并转发源消息的线性组合，并基于晶格代码的代数结构。如果收到足够的线性方程，目的地将恢复所有传输消息。在这项工作中，我们在系统级别设计，基于FINCKE-POHST的候选候选算法和网络编码系统矩阵构建算法的计算和前向网络编码系数，使得拟议算法，多源多余层系统的传输速率是最大化的。数值结果证明了我们提出的算法的有效性。
Network coding is a new and promising paradigm for modern communication networks by allowing intermediate nodes to mix messages received from multiple sources. Compute-and-forward strategy is one category of network coding in which a relay will decode and forward a linear combination of source messages according to the observed channel coefficients, based on the algebraic structure of lattice codes. The destination will recover all transmitted messages if enough linear equations are received. In this work, we design in a system level, the compute-and-forward network coding coefficients by Fincke-Pohst based candidate set searching algorithm and network coding system matrix constructing algorithm, such that by those proposed algorithms, the transmission rate of the multi-source multi-relay system is maximized. Numerical results demonstrate the effectiveness of our proposed algorithms.
