| 摘 要： | Ultra-Wideband(UWB)技术被认为是最适合进行室内无线定位的技术。为了实现对基于UWB的物联网中节点的位置进行定位及对算法进行仿真,采用Matlab仿真了PPM-TH-UWB(Pulse Position Modulation Time Hopping UWB)信号在IEEE802.15.4a信道下的发射、延时、衰减、信道冲击响应、加噪声、相关接收、节点定位。该方法解决了在没有UWB信号发送、接收装置时对无线定位算法的仿真、测试和评估。 |

| Abstract: | Ultra-Wideband (UWB) technology is considered the most suitable for indoor wireless location technology. In order to achieve the location of the nodes in UWB-based Internet of Things (IoT) and the simulations of the location algorithms, Matlab was used in the article to simulate the PPM-TH-UWB signal in IEEE802.15.4a channel model, which included the emission, delay, attenuation, adding noise, channel impulse response, correlation receiver and location of the nodes. The proposed methods can realize the algorithm simulations for positioning, testing and evaluation of wireless location in the absence of the UWB sending and receiving device. |
