Mathematical Model Of Telecommunication System With MIMO 3x3

Abstract

we propose a method for a complete mathematical model developing of TCS with MIMO 3x3 using the theory of vector and matrix analysis. In this case, complex parameters are used that characterize the radio channels, antenna signals and signal processing devices in the receiver. A mathematical model for the system of the signal-to-noise ratio at the output is developed, which allows to determine the reception error of the signal with this type of manipulation. It is emphasized that the proposed method can be used to study the system with any number of transmitting and receiving antennas. Attention is paid to the need of taking into account the peculiarities of the signal propagation in radio channels, antenna orientation and signal processing in the RAKE receiver.
