Indoor wireless communications with multiple antennas and polarizations: From channel characterization to performance simulation

In this paper, we describe experimental results characterizing the frequency/space/polarization selectivity of indoor channels at 1.9 GHz. Regarding the delay-angle dispersion, a clustered geometry-based model is developed from measurement results and validated. Regarding dual-polarized channels, a simple analytical model is extracted from experimental data, accounting for the cross-correlation between the various parameters. Finally, narrowband dual-polarized and single-polarized transmissions are compared in real-world indoor channels based on performance metrics for multiplexing and diversity gains.
