RADIO COMMUNICATION DEVICE AND RADIO COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a technique to cancel an echo depending on a selected transmission antenna in an SM transmitter in which a transmission antenna is switched depending on a transmission signal.SOLUTION: A radio communication device comprises: a plurality of antennas 122 and 123; antenna selection means 106 for selecting a transmission antenna from the plurality of antennas depending on a transmission signal at the time of transmission; and interference cancelling means 120 for generating a signal for cancelling interference. The interference cancelling means 120 is configured to change the signal for cancelling interference depending on the selected transmission antenna.
