Abstract
The present invention relates to techniques for OTA testing suitable for producing a test signal to emulate a wireless channel while using a limited number of transmit elements. The techniques described herein enable the number of transmit antennas used to emulate a given signal path in an emulated wireless channel to be less than the number of sub-paths used to characterize the angle spread of the given signal path. As a result, a test setup is provided having a relatively small number of transmit antennas which also accurately maintaining the desirable characteristics of the emulated wireless channel.
