Zusammenfassung: | Provided in some embodiments of the present application is a method for reconstructing an intermodulation interference signal, which is used in a multi-carrier system that uses a specific frequency band. The method comprises: acquiring (201) a digital downlink signal that comprises a useful signal and an intermodulation interference signal; from a model library that comprises an amplitude calculation model corresponding to each frequency point that generates intermodulation interference, selecting (202) an amplitude calculation model corresponding to each frequency point in a frequency band where the useful signal is located; on the basis of a local uplink signal in baseband form and the selected amplitude calculation models, determining (203) the amplitude of each frequency point in an intermodulation interference sequence; and on the basis of the gain of an intermodulation interference channel at each frequency point and the amplitude of each frequency point in the intermodulation interference sequence, rec |
