Evaluation of propagation characteristics in indoor environment for MIMO system

This paper presented that receiver correlation was lowered by using dual polarized antenna array in both the LOS and NLOS environments. In the LOS environment, the difference of the angle of polarization made no difference for both of the single and the dual polarization case, and the advantage of eigenvalues for dual polarization worked effectively. On the other hand, in the NLOS environment, although the advantage of eigenvalue for the dual polarized case was observed, it didn´t overwhelm the power loss deriving from dual polarization. This is because the V component became dominant comparing the H component with the existence of partition, which gave high SNR and capacity to the single V polarized case in the calculated model. Finally, it is necessary to reexamine these results in more realistic simulation model and in experimental method.
