Patent ID: 8787900

Claim:
A system used to test a cell phone that uses multiple cell phone antennas, including: at least one signal feed adapted to be coupled to the cell phone at a location that bypasses the cell phone antennas, whereby the cell phone performs multiple-input/multiple output, abbreviated MIMO, processing of multiple signals from the multiple cell phone antennas; at least one memory; and one or more channel generator modules running on one or more processors, coupled to the signal feed and the memory, wherein each channel generator module: uses at least three correlation data sets stored in the memory to emulate different channel conditions of a propagation channel model (abbreviated “PCM”), the correlation data sets representing time-varying reorientation of the multiple cell phone antennas; and conditions a test signal with the different channel conditions and passes the conditioned test signal to the signal feed; and a measurement module running on one or more of the processors, coupled to the signal feed, that measures response of the cell phone to the conditioned test signal.
