A new semi-deterministic model for MIMO systems

To model modern wireless communication systems such as MIMO systems, new types of channel are required to be characterized by modern models which consider spatial properties of radio channel as well as temporal ones. In this regard, we chose to develop a mathematical model, Single Interaction ScatTEring Reflecting (SISTER), which is a semi-deterministic channel model. This model is applicable to arbitrary antennas and includes array factor in the case of using antenna array and is suitable for channel prediction studies in both indoor and outdoor environments. In the SISTER model, different distributions for scatterers and in the case of indoor environments, different dimensions for a room can be assumed. The corresponding algorithm calculates the direct path, reflected and scattered electric fields and finally computes the channel capacity in a short time.
