工业无线网络Krylov子空间估计与动态信道选择
Krylov subspace estimation and dynamic channel choice of industrial wireless network
摘要
Abstract
In industrial wireless sensor networks, the performance of channel should be estimated and the operating chan-nel should be selected to ensure reliability of communication. Based on analysis of industrial noise, the model of frequency selective receiving channel of Krylov subspace is established, and the time-space performance of receiving signal is ana-lyzed. According to the analysis of channel estimation, a method of dynamic channel selection which judges the quality of channel based on time delay is introduced. Experimental results show it can increase 2 meters of communication distance, and can reduce the packet loss rate 30%or so.关键词
