Patent ID: 8798549

Claim:
A radio communication device comprising: a carrier reproduction filter which is configured to eliminate a noise component from a carrier phase signal detected from a received baseband signal; a carrier reproduction part which is configured to reproduce a carrier signal based on the carrier phase signal; a reception part which is configured to implement carrier synchronization using the carrier signal; a phase noise information extraction part which is configured to extract a transmission-side phase noise characteristic from a radio frame demodulated from the carrier signal; and a filtering characteristic selection part which is configured to calculate integrated phase noise characteristics by adding a predetermined reception-side phase noise characteristic to the extracted transmission-side phase noise characteristic and which is configured to select a filtering characteristic based on comparison between a predetermined threshold and the integrated phase noise characteristics, wherein the filtering characteristic selection part selects a broadband filtering characteristic with respect to the integrated phase noise characteristics higher than the threshold while selecting a narrowband filtering characteristic with respect to the integrated phase noise characteristics lower than the threshold.
