uwb ultra wide band 2019

Ultra-Wide Band (UWB) is a communication method used in wireless networking that uses low power consumption to achieve high bandwidth connections. In other words, it’s meant to transmit a lot of data over a short distance without using too much power

Modeling and Simulation of UWB Signal for Indoor Radio Channels
free download

In this paper, we describe the indoor radio channel characteristic of Ultra-wideband signals by computer simulation. To analyze the propagation characteristic of UWB radio signals, we used the parameter proposed by IEEE P802. 15 WPANs in 2003. From the simulation
