Abstract

We present an improved model for outdoor MIMO wireless channels and its spatial fading correlation and capacity performances. The proposed model is more representative than the traditional independently and identically distributed (i.i.d) model by considering the remote scatterers on top of the "one-ring" model. We consider both local and remote scatterers with respect to the receiver for modeling the urban macrocellular wireless environment. The channel capacity for a given structure of scatterers and a set of physical parameters including the antenna pattern and propagation loss has been investigated. As a result, the fading correlation is expressed as a function of the scattering characteristics as well as the propagation parameters of the MIMO channels. We provide detailed analysis on the effect of correlation due to the increased number of scatterers and the capacity results obtained via extensive simulations. Using the proposed model we show the combined correlation and scattering effect on the capacity of MIMO systems and the difference on the capacity performance between the proposed macrocellular model and the "one-ring" model.
