Ultra-Wideband Outdoor Communication Characteristics With and Without Traffic

Provided by: EURASIP Topic: Networking Date Added: Mar 2012 Format: PDF
The BER performance for Ultra-WideBand (UWB) outdoor communication in LOS and NLOS environments with and without traffic is investigated. The authors obtain the impulse responses of the UWB outdoor environment by both 2.5D SBR-Image method and inverse Fourier transform techniques. The 2.5D SBR-Image method is first considered for two-dimensional environment simulated without heights of obstacles by ray tubes. Then, heights of the obstacles are taken into consideration between the transmitters and receivers. If the height of ray is lower than that of obstacles, the ray is neglected for the receivers. This effectively reduces the simulating time.
