External PIM Modeling in FDD MIMO

In this paper, a physical approach is proposed to describe external (air-induced) passive intermodulation (PIM) for a frequency-division duplexing (FDD) multiple-input multiple-output (MIMO) system with an arbitrary number of transceiver chains. It is caused by metallic objects with nonlinear charac...
