UWB Ultra-wideband-2020

Ultra-wideband (also known as UWB, ultra-wide band and ultraband) is a radio technology that can use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum. UWB has traditional applications in non-cooperative radar imaging

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
