Abstract
This letter discusses one aspect of over-the-air (OTA) testing for multiple-input-multiple-output (MIMO) capable terminals in flexible multiprobe setups. Two techniques to obtain weights as well as angular locations for the OTA probes are proposed for accurate reconstruction of the channel spatial correlation at the receiver side. Examples show that with a small number of probes in a flexible setup, accurate spatial correlation can still be achieved within the test zone.
