Method and transceiver for cancelling multi-carrier transmission interference

A transceiver, comprising a transmitter and a receiver, and further comprising a processor for cancelling multi-carrier transmission interference;

• wherein the processor is further configured to collect a high order intermodulation signal in radio frequency signals output by a transmitter and to process the high order intermodulation signal so as to generate a first digital signal;
• the processor is configured to establish a high order intermodulation model by using the first digital signal and a first baseband signal output by the transmitter and to generate a second digital signal by using a coefficient of the high order intermodulation model and a second baseband signal output by the transmitter;
• the processor is further configured to counteract interference in a digital signal output by a receiver with the second digital signal;
• wherein the processor is configured to perform adaptive balancing on the second digital signal, wherein the processor performs the adaptive balancing on combined multiple carriers or performs the adaptive balancing separately on each carrier;
• and the processor is configured to subtract the second digital signal that has been adaptively balanced from the digital signal output by the receiver.
