Fading Channel Modeling for Fixed Mobile Terminal in Outdoor NLOS Environment

Mobile terminals used in the stationary condition experience a level variation different from that found in the moving condition. Therefore, it is very important to study the fading characteristics of static usage. This paper clarifies the generalized fading characteristics of mobile terminals in outdoor NLOS environments when they are used in the stationary condition; only adjacent objects such as vehicles move. A general empirical formula of the autocorrelation function of the received level is derived that considers the speed and size of vehicles as physical parameters. We explain this empirical formula theoretically by using a simple analysis model. Furthermore we analyze the power spectrum of received level variation in order to easily generate the channel variation.
