| 摘要 |
The present invention has a configuration, by which a frequency deviation estimation circuit (10) detects a frequency deviation DELTA f of a timing clock in a receiving duration, using a high-speed and high-accuracy system clock, and a tau estimation circuit (51) of a CPU (50) obtains a timing correction tau from the detected results. And then the tau estimation circuit (40) corrects the receiving timing obtained in a non-receiving duration by a timer (30), using the timing clock by the timing correction tau to start the receiving in the receiving duration according to the corrected receiving timing. <IMAGE> |
