In a multiple-input multiple-output (MIMO) system, cross-polarized antenna selection yields significant reduction in cost and hardware size. However, actual benefits of the technique are dependent on the propagation characteristics including channel polarization. To accurately characterize the target 2GHz-band MIMO channels, the authors conduct 2GHz cross-polarized channel measurement campaigns. Based on the measured data, novel channel models specifically for the 2 GHz band are established. In this paper, we evaluate the performance improvement obtained with cross-polarized antenna selection using the channel models. Simulation results reveal that antenna selection is particularly useful in the low SNR regime, and that the average system capacity at cell edges can be increased up to 15%. |
