Method of correcting frequency error

Frequency error's adjusting method. The invention claims a adjusting method at the frequency for error in CDMA internal mobile wireless communication terminal, using the method in adapted to the value of frequency error. Therefore, the invention uses three or a handle mode frequency adjusting: errorMethod for with a can not full, a corresponding to the open loop and rough adjusting, finally is a corresponding to the closed-loop method of pulse adjusting. The frequency error of the flexible mode of a central processing unit (6), and a handle according to the value of frequency error, the other side according to chosen is a channel coefficient filtering module (3) quality control unit (7) for determining quality factor (qual_est).
