This paper presents some results obtained from a first approach to a point-scatter simulator for Multiple-Input Multiple-Output (MIMO) radio channel modeling. Specifically, the authors present the comparison of capacity obtained using the point-scatter simulator with that obtained with the Kronecker model. Capacity results obtained from measured propagation data are also presented. Ideas to enhance the simulator, which include the development of a statistical-based generative channel model for MIMO systems, are discussed. The demand for higher data rates, the limited bandwidth and power constraints in wireless communications have pushed research for solutions that efficiently make use of available resources. The harsh wireless channel is usually characterized by multipath propagation leading, among other phenomena, to random fading.
