A radio communication device reproduces a carrier signal by eliminating phase noise from a carrier phase signal detected from a received baseband signal. Herein, a filtering characteristic having a default value is adopted to eliminate phase noise from the carrier phase signal with respect to a firstly received baseband signal. Integrated phase noise characteristics are calculated by adding a transmission-side phase noise characteristic, which is extracted from a radio frame demodulated from the carrier signal, to a predetermined reception-side phase noise characteristic. An optimum filtering characteristic is selected through comparison between a threshold and integrated phase noise characteristics. The selected filtering characteristic is adopted to eliminate a noise component from the carrier phase signal with respect to a subsequent baseband signal.
