PROBLEM TO BE SOLVED: To provide the improved performance and power consumption of a radio communication system by effectively canceling third-order intermodulation distortion (IM3) in LTE signal transmission.SOLUTION: A transceiver device 1100 includes: a transmission path 1164 for generating a transmission signal modulated on the basis of a base band signal; and a reception path 1162 for receiving a reception signal receiving the influence of a third-order distortion due to an intermodulation noise generated by intermodulation between a continuous wave blocker and transmission leakage from a transmission path. The transceiver has a compensation path for modeling the portion of a transmission path and a reception path, and for generating a replica signal indicating the third-order distortion in accordance with a specified function and the modeled portion of the transmission path and the reception path. The compensation path filters the replica signal, and subtracts the filtered replica signal from the reception signal for removing the third-order distortion due to the intermodulation noise. |
