Modelling and simulation of an indoor radio channel at 20 GHz

Abstract

This paper reports the results of measurements and analysis of the indoor radio propagation channel at 20 GHz. The experiment consisted of taking impulse response measurements in several locations corresponding to typical office environments while varying numbers of users carried out normal daily activities. This paper presents some of the parameters extracted from the measured impulse responses which characterise the channel and details the parameter extraction process used. These parameters are used in a channel simulation model and the output of this simulation is compared to the original data on the basis of direct and multipath amplitudes and probability density functions.
