In this paper, the time-space correlation function for narrowband MIMO channels is derived. We consider two 3D models, the cylinder model and the sphere model. In both cases, Rician fading is assumed. Scatterers are assumed around the mobile station alone to model macrocell situation. The results show that under reasonable assumptions, both models simplify to the 2D model proposed in . Eventually, the construction of the correlation matrix used in the vector autoregressive (VAR) simulation method is studied. 2008 IEEE.
