Wireless apparatus and distortion compensation method used on time division duplex system

摘要

There is provided a wireless apparatus in which a distortion compensation loop is formed so as to compensate nonlinear distortion of a transmission amplifier (1), being used on a time division duplex system on which a wireless signal is transmitted in a transmission time period with same frequency as being received, the wireless apparatus used on the time division duplex system including a combining section (8) to combine a feedback signal (102) into which a return signal generated by reflection of a transmission signal at a antenna leaks and the return signal processed by a reception unit (7) to process a reception signal from the antenna in the transmission time period so as to cancel the return signal leaked into the feedback signal (102).
