Query: Millimeter-Wave Over-the-Air Signal-to-Interference-plus-Noise-Ratio
  Measurements Using a MIMO Testbed   In this paper, over-the-air experiments with external and internal
interferences were performed using Chalmers millimeter-wave
multiple-input-multiple-output testbed MATE. The resulting SINR for both
interference experiments are compared and discussed.
