This paper presents a methodology of controlling the spatial correlation of BS (base station) antenna realized by a bilateral fading emulator for MIMO-OTA (Over-The-Air) testing. On the basis of Jakes theory, the base station correlation is controlled by setting the initial phases of scatterers in a two-dimensional fading emulator. The experimental results show that the designed correlation coefficient of an uplink channel using the proposed method agrees well with the theoretical value. Further, it is confirmed that the channel capacity of uplink channel can be controlled when the base station and mobile terminal correlations are changed simultaneously.
