An Evaluation of Distortion and Interference Sources Originating Within a Millimeter-Wave MIMO Testbed for 5G Communications

This paper presents an evaluation of distoration and interference source, namely, the harmonic distortion and antenna crosstalk, originating within a 2 × 2 millimeter-wave (mm-wave) multiple-input-multiple-output(MIMO) testbed. The experience gained through the insight into the built testbed could be fed into the design of future mmwave massive MIMO testbeds.
