发明名称 WIRELESS COMMUNICATION APPARATUS AND FREQUENCY DEVIATION CALCULATION METHOD
摘要 <P>PROBLEM TO BE SOLVED: To improve reception quality of opposite wireless communication apparatus moving at high speed and at low speed. <P>SOLUTION: A frequency deviation-calculating means 1 of a wireless communication apparatus calculates frequency deviation of a received radio signal from the reception frequency of the relevant wireless communication apparatus. An averaging means 2 averages the frequency deviation calculated by the frequency deviation-calculating means 1. On the basis of the frequency deviation calculated by the frequency deviation-calculating means 1, a moving speed calculating means 3 calculates the moving speed of the opposite wireless communication apparatus that wirelessly communicates with the wireless communication apparatus. On the basis of the moving speed of the opposite wireless communication apparatus calculated by the moving speed calculating means 3, an average time change means 4 changes the average time of the frequency deviation of the averaging means 2. <P>COPYRIGHT: (C)2010,JPO&INPIT
