An Orthogonal Polarization Based MIMO Transmission for Advanced 60GHz WLAN
An orthogonal polarization based MIMO transmission scheme is proposed to achieve over 10Gbps transmission for advanced 60GHz WLAN. As the proposed MIMO transmission scheme uses V(Vertical)/H(Horizontal) polarization directional antennas, stable 2×2 MIMO transmission is enabled even in LOS (line-of-sight) environment. A ray-tracing method is employed for computer simulation to evaluate channel capacity and BER performance of the proposed scheme in indoor conference room environments. The simulation results confirm that the proposed orthogonal polarization based MIMO transmission scheme achieves higher channel capacity than the conventional MIMO transmission using the same polarization antenna. Furthermore, this paper shows that BER performance depends on the location of transmitter and receiver as well as the beam-width of the directional antenna. BER performance is significantly degraded when the antenna height of the transmitter is the same as that of the receiver. On the other hand, better BER performance can be achieved when the antenna height difference is large.
