Method of performing automatic frequency control in a mobile station during communication mode |
摘要 |
An AFC process is performed even when a mobile station is in a speech communication mode in which a data channel is being received by a finger receiver. In the speech communication mode, a frequency error measuring unit measures a frequency error of the data channel. An AFC circuit performs an AFC process for controlling the frequency of a TCXO, i.e., a reference oscillator, using the measured frequency error. No reception failure occurs even when the TCXO suffers frequency fluctuations in the speech communication mode. <IMAGE> |
