METHOD AND APPARATUS FOR CARRIER FREQUENCY OFFSET ESTIMATION AND FRAME SYNCHRONIZATION IN A WIRELESS COMMUNICATIONS SYSTEM

摘要

A method for performing carrier frequency offset estimation and frame synchronization is disclosed herein. In one approach, the method includes performing a first level frequency discrimination on at least one estimated channel tap to generate a frequency discriminated value; estimating a phase error from the frequency discriminated value; and, detecting a predetermined frame synchronization pattern from the frequency discriminated value. A computer program product having code and a wireless communications apparatus for performing the method are also described herein.
