A hyperbolic MIMO channel model for macrocell

This paper presents a multiple-input multiple-output (MIMO) space-time geometrical channel model with hyperbolically distributed scatterers for a macrocell mobile environment. The model is based on a one-ring scattering assumption. This MIMO model provides statistics of the time of arrival (TOA) and direction of arrival (DOA). It is assumed that there is no line of sight (LOS) between the transmitter and the receiver, and that the scatterers around the mobile station (MS) are arranged in a circular way. The temporal autocorrelation function (ACF) and spatial cross-correlation function (CCF) are presented, and the model is examined under different mobile environments, physical parameters (such as the scattererspsila distribution), and system parameters (such as the antenna spacing). The transmitter motion is considered.
