Abstract

We present the results of multiple-input multiple-output (MIMO) indoor channel measurements in the 5.25 GHz band, emphasizing the case where both transmitter and receiver apply dual-polarized antennas. Wideband (100 MHz) capacity results show that dual-polarized antennas provide an attractive solution for MIMO multiplexing. This is due to the fact that the static component in a line-of-sight (LOS) channel preserves its polarization, and channels between dual-polarized antennas may still remain separated. This is not necessarily the case if spatially separated copolarized antennas are applied.
