Abstract:
This invention presents a RF channel emulator for testing a large-scale Multiple-User Multiple-Input Multiple-Output (MU-MIMO) wireless communication system, including embodiments of using over-the-air channels for connecting a RF channel emulator and a large-scale MU-MIMO wireless communication system, calibration processes that maintain the over-the-air channel reciprocity, and emulation of carrier aggregation.

Claim (Index 25):
The apparatus in  claim 21  further comprising a module that receives one or more pilot signals transmitted from the BS, estimates the channel matrix between the BS and apparatus; and applies the inverse or pseudoinverse of the channel matrix to the baseband digital signals to remove the effect of the channels of the connections between the BS and apparatus, wherein the wired or over-the-air (OTA) wireless interface for connecting the apparatus with a Base Station (BS) produces a channel matrix of rank not less than M.
