METHOD AND APPARATUS FOR COMPENSATING FREQUENCY OFFSET OF RANDOM ACCESS SIGNALS

摘要

A method and an apparatus for compensating frequency offset of random access signals are disclosed in the present invention. The method includes: receiving the random access signals, then acquiring a peak value detection sequence (301); compensating the frequency offset for the cyclic shift sequence according to the relationship between a main peak value and a subsidiary peak value of a cyclic shift sequence in the peak value detection sequence (302); detecting the peak value in the compensated cyclic shift sequence (303). The present invention can eliminate the deterioration of missed detection performance and false alarm performance caused by the frequency offset while detecting the random access signals, increase the accuracy of the detection, and save resources.
