Abstract: Frequency-division duplex (FDD) systems face the interference of passive intermodulation (PIM) caused by nonlinear distortion of transmitted signals. This type of self-interference problem is more serious in FDD multiple-input multiple-output (MIMO) systems. Because large-scale antenna… read more here.
