There is provided a wireless apparatus in which a distortion compensation loop is formed so as to compensate nonlinear distortion of a transmission amplifier, 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 to combine a feedback signal 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 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.
