摘要：
A frequency error detector and combiner for use in a mobile communication system. The frequency error detector and combiner for use in a receiver of a mobile communication system which includes different frame formats according to slot formats, the receiver having at least two fingers including a frequency error detector for detecting a frequency error using a phase reference symbol of a predetermined channel received from a transmitter and a reference frequency error generator for generating a reference frequency error at predetermined reference time intervals using the detected frequency error; a level controller for controlling the gain of a frequency error generated from the reference frequency error generator; and a frequency error combiner for combining the gain controlled frequency error generated from each finger with a predetermined value.
