摘要:
This invention presents embodiments of a coupler array to couple the RF signals between the antenna array of a MIMO base station and a MIMO RF channel emulator. The embodiments enable testing of a large scale MIMO wireless communication system without the need of connecting a large number of RF cables to the antenna ports of the MIMO base station.
