Because the CORDIC algorithm can change the arctan function and round of angle to addition and shift operation, the novel model presented in the paper can complete frequency offset estimation and correction in digital field in the same time.

• 由于CORDIC算法能把复杂的反正切函数求解和角度旋转操作转化为简单的移位和加法操作,文中所给出的同步模型可在数字域同时完成频率偏移估计和频率偏移校正。
