Indoor field experiment results on spatial multiplexing MIMO using dual-polarized antennas

This paper describes the performance of MIMO (multiple Input Multiple Output) system using dual-polarized antenna in a IEEE 802.16m. The use of dual-polarized antennas in MIMO systems has emerged as a cost-and space-effective alternative, where two spatially separated uni-polarized antennas can be replaced by a single antenna element employing orthogonal polarizations. Several papers show mainly polarization diversity in multiple antenna system so far. In this paper, we show the simulation results of spatial multiplexing(SM) and space frequency block codes (SFBC) MIMO employing dual-polarized antenna. Also, we measure the PER (packet error rate) of downlink signal in implemented SM and SFBC MIMO system which is employing dual-polarized antenna under the indoor field environment. Dual-polarized antenna system achieved the similar trend PER (packet error rate) curve with uni-polarized one. That means that multiplexing gain is obtained from polarized antennas system having space and cost effective.
