Fading channel modeling for fixed terminal in outdoor NLOS condition

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 surrounding objects such as cars move. A general empirical formula of the autocorrelation function of the received level is derived considering the speed and size of cars at the same time as physical parameters. Furthermore, we explain this empirical formula theoretically by using a simple analysis model.
