It is well known that the method of ray tracing tubes could be used to predict the propagation of radiowave in complex environment. Moreover, it is an important technology used to explore the characteristics of indoor radiowave propagation. But the traditional methods could not compute the path vector correspond to diffraction ray tube when ray which ray tube intersect with the obstacle such as furniture...
A line-of-sight (LOS) signal propagation experiment in frequency domain is performed under a typical short-range indoor environment for wireless sensor networks (WSN) applications. In the measurement, the signals have nominal center frequency of 5.8GHz. Based on measured datum, cumulative distribution of RMS delay spread is modeled as approximately normal distribution. Then, a multi-path fading channel...
Regarding a transmitter and a receiver as two fixed points of the Brownian bridge process, an ultra-wideband (UWB) multipath as a trajectory of the Brownian bridge process, all reflection points of paths situating on the surfaces of obstacles, and adopting two-value phase assumption, a bounded Brownian bridge model (BBBM) for UWB indoor multipath channel is constructed. Using BBBM to simulate a corridor...
