Abstract
The development of wireless communication systems tends to be high-power, multi-carrier and broadband, which makes the problem of passive intermodulation (PIM) interference in the communication systems more and more serious. When PIM interference falls into the receiving passband of communication systems, the receiving sensitivity of receivers will be reduced and the performance of the receiver will be affected. In this paper, a model is established to analyze the influence of PIM interference on the demodulation link in two cases. One is the constant signal-to-interference ratio (SIR), and the center frequency of PIM interference is the same as the carrier frequency of the uplink received signal, the other is time-varying SIR. Due to numerical simulations, the analysis curve and simulation curve of the bit error rate is basically consistent with each other, indicating that the analysis model is reasonable.
