FREQUENCY CALIBRATION METHOD AND DEVICE

摘要

Disclosed are a frequency calibration method and device, the method comprising: a determination is made about whether the frequency error of a signal transmitted by a terminal in relation to a center frequency is within a first pre-set range, when a first register of the terminal is set to a first pre-set value; if the determination is positive, a determination is made about whether the frequency error of the signal transmitted by the terminal is within a second pre-set range, when the first register of the terminal is set to the first pre-set value and a second register of the terminal is set to a second pre-set value; if the determination is positive, the frequency change of the signal transmitted by the terminal under the control of the first register and the second register, the first pre-set value, and the second pre-set value are acquired after the value of the second register is changed. The present invention enables a terminal to conduct precise frequency calibration and effectively adjusts the terminal transmission frequency to a center frequency, thereby enhancing the precision of the terminal transmission frequency with simple implementation and with no need for complex instruments or algorithms.
