SIGNAL PROPAGATION MODELING IN MIMO COMMUNICATION SYSTEMS

The fundamentals of MIMO systems of information transmission are considered and the equivalent schematic diagram of the system in accordance with the mathematical model of the communication channel is drawn up. The throughput calculation of MIMO communication system is performed, modeling was carried out and dependences of throughput on the number of antennas and signal-to-noise ratio were obtained. For the case of joint propagation of direct and scattered beams, a channel model based on the channel coefficient matrix with regard to the energy ratio between beams is considered and the capacity dependence at different values of the Rice coefficient is obtained.
