Numerical analysis method for wireless channel of MIMO system

Abstract

A numerical analysis method for the wireless channel of the multiple-input multiple-output (MIMO) system is proposed. This method is a hybrid of the finite difference time domain (FDTD) method and the method of moment (MoM), and is capable of analyzing the MIMO system including the propagation channels consisting of scatterers with arbitrary location and structure, and the transmitting and receiving antennas with arbitrary geometry. Bit error rate (BER) and channel capacities of the MIMO systems are calculated and shown by changing the received SNR, the number of antenna elements, the array spacing and the scatterers located in the propagation channel.
