The inter- and intrasite correlation properties of shadow fading and power-weighted angle spread at both the mobile station and the base station are studied utilizing narrowband multisite MIMO measurements in the 1800 MHz band. The influ

This paper proposes several configurations for multiple base stations in indoor MIMO systems and compares their performance. The results are based on channel measurements realized with a MIMO testbed. The receiver was moved along several routes and f

12th European Conference on Antennas and Propagation (EuCAP 2018).
A set of propagation models for site-specific path loss and channel predictions are introduced. These include a half-screen model for propagation above buildings and terrain and efficient modeling of propagation around buildings including hybrid abov

In this paper we predict spatial wireless channel characteristics using a stochastic model that takes into account both distance dependent pathloss and random spatial variation due to fading. This information is valuable for resource allocation, inte
