This paper introduces a general concept of a space time geometrical channel model with hyperbolically distributed scatterers for a macrocell mobile environment. This model provides statistics of the time of arrival (TOA) and direction of arrival (DOA). The proposed channel model is modified to Multiple Input Multiple Output (MIMO) model which characterizes the space and time-variance characters of the mobile radio channel. Our MIMO channel model is based on one-ring scattering model. This model is examined under different mobile environments. Moreover, we studied the influence of the physical parameters (such as scatterers distribution) as well as the system parameters (such as antennas spacing) on the capacity.
