Description
Summary:This paper presents ultra-wideband (UWB) indoor propagation channel measurement techniques and results for the parameters of an empirical channel model. To analyze the channel impulse response an improved technique is applied to remove the parasitic effects of the employed hardware properly. The transmission between the ports of a transmit (TX) and receive antenna (RX) is measured with a vector network analyzer (VNA). As the impulse responses of the antennas are deconvolved from the measurements, the channel transfer function in the frequency range of 2-8 GHz can be determined. This approach is applicable as omnidirectional antennas with almost angularly independent impulse responses are used. A statistical model is employed, based on a large database measured in a commercial indoor environment. The measurements include line-of-sight (LOS) and non-line-of-sight (NLOS) scenarios, where the distance between the transmitter and receiver is varied from 1-5.5 m. To characterize small-scale and large-scale statistics of the channel, at each receiver position 25 measurements are accomplished over a grid with 5times5 spatial points.
