Distortion cancellation apparatus and distortion cancellation method

A distortion cancellation apparatus comprising:

• a memory;
• and
• a processor coupled to the memory and the processor configured to:
• acquire a plurality of transmission signals to be wirelessly transmitted at different frequencies;
• acquire a first plurality of reception signals to which an intermodulation signal generated due to the plurality of transmission signals wirelessly transmitted is added;
• multiplex at least one set of reception signals among the first plurality of reception signals so as to generate at least one multiplexed reception signal;
• generate a cancellation signal for canceling the intermodulation signal, based on the plurality of transmission signals to be wirelessly transmitted and the at least one multiplexed reception signal;
• cancel the intermodulation signal added to the at least one multiplexed reception signal, based on the cancellation signal;
• and
• demultiplex the at least one multiplexed reception signal from which the intermodulation signal has been canceled, into a second plurality of reception signals.

• multiplexing at least one set of transmission signals among the plurality of transmission signals to be wirelessly transmitted so as to generate at least one multiplexed transmission signal;
• generating a cancellation signal for canceling the intermodulation signal, based on the at least one multiplexed transmission signal and the plurality of reception signals;
• and
• cancelling the intermodulation signal added to the plurality of reception signals, based on the cancellation signal, by a processor.
