- Abstract
- A frequency error estimator and an operating method of the frequency error estimator are provided. In the frequency error estimator and the operating method of the frequency error estimator, a frequency error between a transmitter and a receiver of a mobile communication system using a reference code is calculated, thereby improving the precision of estimation while reflecting variations in frequency over time.
