Abstract:
There is provided a communication device including a first transmitter configured to up-convert a frequency of a first transmission signal to a first frequency so as to be wirelessly transmitted, a second transmitter configured to up-convert a frequency of a second transmission signal to a second frequency different from the first frequency so as to be wirelessly transmitted, a receiver configured to receive a reception signal including a passive intermodulation signal generated due to the first and second transmission signals wirelessly transmitted, a memory, and a processor coupled to the memory and configured to estimate frequency errors of the up-converted first and second transmission signals, generate a cancellation signal into which any frequency of the first and second transmission signals has been corrected, based on the estimated frequency errors, and combine the cancellation signal with a down-converted reception signal.

Claim (Index 16):
A cancellation device comprising:\n a memory; and a processor coupled to the memory and the processor configured to: acquire a first transmission signal having an up-converted first frequency and a second transmission signal having an up-converted second frequency different from the first frequency, the up-converted first and second transmission signals to be wirelessly transmitted; acquire a reception signal including a passive intermodulation signal generated due to the up-converted first and second transmission signals wirelessly transmitted, and down-convert the reception signal to a baseband signal; estimate frequency errors of the up-converted first and second transmission signals; generate a cancellation signal into which any frequency of the first and second transmission signals has been corrected, based on the estimated frequency errors, wherein the cancellation signal is a replica signal for the passive intermodulation signal; and combine the cancellation signal with the down-converted reception signal.
