Abstract
For research on channel characteristics of dual-polarized multiple input multiple output (MIMO) system, the channel measurements were carried out using Elektrobit multi-dimensional radio channel sounder for line-of-sight and non-line-of-sight routes in indoor office. The channel characteristics were investigated by the power delay profile, root mean square delay spread, channel capacities and cross polarization discrimination. It can be found that the parameters have different propagation behaviors in horizontal polarized, vertical polarized and dual-polarized case. The simulation results show that dual-polarized MIMO system will increase the multipath components, and the channel capacity can be significantly improved compared to single-polarized. The results in this paper are critical for indoor MIMO system design as well as for link and system level simulations.
