Abstract :
The effect of antenna locations on multiple-input-multiple-output (MIMO) communication system in the line of sight (LOS) and the nonline of sight (NLOS) indoor environments is investigated by a numerical hybrid method of the method of moments (MoM) and the finite difference time domain (FDTD) method. The channel capacity, the received power and the effective degrees-of-freedom (EDOF) of multipaths of MIMO system are statistically analyzed. It is found that the channel capacity of indoor MIMO system is affected significantly by the antenna locations. However, in the case of ignoring of path loss, MIMO channel capacity in NLOS indoor environment is almost independent of antenna locations
