Performance of open-loop MIMO precoders in the presence of a line-of-sight component

The performance of open-loop MIMO precoders is evaluated in the presence of a line-of-sight (LOS) component. Furthermore, the performance for the effect of the use of cross-polarized antennas is presented. The simulation results show that the proposed open-loop precoder works well even in the presence of the LOS with cross-polarized antennas.
