Measurements of Large-Scale Parameters of a Distributed MIMO Antenna System in a Microcell Environment at 2.6 GHz

• Multi-site multi-antenna measurements for semiurban microcell environment at 2.6 GHz are performed with four base stations (BSs) and one mobile station (MS). Three BSs are provided with four antenna elements in closely spaced copolarized configuration, and one BS is provided with a single antenna element. The MS is equipped with a cylindrical uniform array consisting of 64 dual-polarized antenna elements and moves along some predefined routes. The values of large-scale fading (LSF) from 19 measurement runs with a total of 1900 snapshots at different locations are extracted. The cross-correlation properties of the LSF between different BS links are analyzed. It was found that, in the selected propagation environment, the influence of the BS location on the LSF cross-correlation properties is negligible. However, the location of the MS has a significant influence on the LSF cross-correlation properties of the different BS links.
