APPARATUS, AND ASSOCIATED METHOD, FOR ESTIMATING FREQUENCY OFFSET OF A DATA SYMBOL COMMUNICATED IN A COMMUNICATION SYSTEM

摘要

Apparatus, and an associated method, for estimating frequency offset introduced upon symbols of a sequence communicated by a sending station to a data destination during operation of a communication system. A received sequence (104) is rotated by multiplying the symbols thereof by offset values selected from a set of offset values (106). Then, for each rotated sequence, an estimation of a data sequence is made (108). Noise indicia associated with each estimated data sequence is calculated (112). And, comparisons are made of the noise indicia associated with each of the estimated data sequences (114). Responsive to the comparisons, selection (116) is made of the frequency offset that has been introduced upon the data sequence.
