Modeling of fading figure for non-stationary indoor radio channels

Fading models of practical mobile radio channel may change over time and/or due to mobility being Rice, Rayleigh, double-Rayleigh, etc, depending on the nature of radio wave propagation, which results in a non-stationary channel. This work is based on investigation of fading figure (FF) that addresses non-stationarity nature of radio channels. The FF is represented by the parameter m of Nakagami-m distribution. For an indoor environment system, our results show the parameter m, which can be modeled as a generalized extreme value distribution. The statistical distribution model of parameter m can be used to study performance of wireless communication system under non-stationary radio channels.
