A MIMO system can offer two types of gains i.e. spatial multiplexing (increase data rate) and diversity gain. However, these benefits of MIMO systems depend crucially on the kind of fading the channels undergo and whether the Channel State Information (CSI) is known at the transmitter. Most of the researches have been on Rayleigh channels. However in real world propagation environment, the fades are not independent, for instance due to insufficient spacing between antenna elements or due to lack of scatterers. It is possible that the Line Of Sight component (LOS) may exist in addition to scattered components.
