Abstract
Disclosed is a frequency error detector and combiner at a receiving end of a mobile communication system. The frequency error detector and combiner using a diversity operation at a reception end of a mobile communication system includes: a plurality of fingers respectively having a diversity combiner for diversity-combining reference symbols used for a frequency error detection, and a frequency error detector for combining output signals of the diversity combiner to generate a frequency offset value; and a frequency error combiner for performing a multipath diversity combination on output signals of the frequency error detector.
Claims2
A frequency error detector and combiner using a diversity operation at a reception end of a mobile communication system, comprising:
- a plurality of fingers each having a diversity combiner for diversity-combining reference symbols used for frequency error detection, and a frequency error detector for combining output signals of the diversity combiner to generate a frequency offset value;
- and
- a frequency error combiner for performing a multipath diversity combination on output signals of each frequency error detector;
- wherein each frequency error detector is connected between its corresponding diversity combiner and the frequency error combiner.
