Claim Text:
1. A method for cancelling multi-carrier transmission interference, comprising: collecting, by an apparatus, a high order intermodulation signal in radio frequency signals output by a transmitter; processing, by the apparatus, the high order intermodulation signal so as to generate a first digital signal; establishing, by the apparatus, a high order intermodulation model by using the first digital signal and a first baseband signal output by the transmitter; generating, by the apparatus, a second digital signal by using a coefficient of the high order intermodulation model and a second baseband signal output by the transmitter; and counteracting, by the apparatus, interference in a digital signal output by a receiver with the second digital signal, wherein the counteracting the interference in the digital signal output by the receiver with the second digital signal comprises:
