Abstract
In this paper we demonstrate the feasibility of a multi-probe based multiple-input multiple-output (MIMO) over-the-air (OTA) test method, where urban macro and microcellular scenarios of the spatial channel model — extended (SCME) are used as a target multipath channel. No work has reported the feasibility of the field synthesis aiming at emulation of the SCME using the plane-wave field synthesis (PWS) based on spherical wave theory so far. In this work we used this technique to emulate the reference channel inside the test area. The feasibility is tested by evaluating the emulated field in terms of four basic channel properties: power delay profile, temporal correlation function, spatial correlation function, and cross polarization ratio. The study shows that feasibility of the PWS technique to emulate all the basic parameters in a multi-probe based MIMO OTA test setup.
