Review and Analysis of Spatial Channel Models in MIMO System

Channel modeling is a fundamental research area in wireless communication due to the complexity of the signal propagation process. To design these new wireless systems, it is essential to use channel models. It plays a crucial role in the investigation of MIMO system capacity. The independent and identically distributed (i.i.d.) channel model has been used by researchers to derive the useful bounds of MIMO capacity. The SCM (Spatial Channel Model) is an example of a more realistic channel model. It is a standardized model developed by 3GPP-3GPP2 spatial channel model (SCM) ad-hoc groups (AHG), which are standardization bodies for 3G cellular systems. This model allows us to perform system level simulations and offers three propagation scenarios for investigation: suburban macro-cell, urban macro-cell and urban micro-cell.
