可扩展的降噪处理和转发双向中继网络

摘要

在这篇文章里面一个可伸缩的继电保护方案是基于一个被叫做降噪和转发的已存在的概念，DNF，我们称之为可伸展的DNF，S-DNF它的目标场景与多个交流流经一个常见的继电器。这个方案的思路是在继电器上组合文件包来节省传输。确保在终端节点上可以解码先验信息结合的内容包必须是可用的。这是聚集在初始传输到继电器。解码之间的权衡和一些必要的传输进行了分析和仿真研究，使S-DNF有能力在高层次SNR上比传统方案提供更好的传输。-In this paper a scalable relaying scheme is proposed based on an existing concept called DeNoise-and-Forward, DNF. We call it Scalable DNF, S-DNF, and it targets the scenario with multiple communication flows through a single common relay. The idea of the scheme is to combine packets at the relay in order to save transmissions. To ensure decodability at the end-nodes, a priori information about the content of the combined packets must be available. This is gathered during the initial transmissions to the relay. The trade-off between decodability and number of necessary transmissions is analysed and simulations show,that S-DNF is able to provide a better trade-off than traditional schemes at high SNR.
