A key point for satisfying the higher data rates that the new wireless communication services demand is to explore and apply several diversity schemes simultaneously. The frequency diversity given by OFDM (Orthogonal Frequency Division Multiplexing) systems increase information of received signals, i.e. Direction-of-arrival (DoA) profiles. In this paper, a proper spatial channel characterization in terms of DoA profiles is conducted using MUSIC algorithm. A MIMO-OFDM testbed is been designed to carried out a measurement campaign in several propagation environments. In order to facilitate the repeatability of taking measurements in the experimental campaign, an automatic positioning system is presented. Several virtual array geometries are studied in terms of DoA resolution | |
