Abstract: A method for performing mobile communications may include comparing a received digitized signal with a local reference synchronization sequence to generate a plurality of candidate timing estimates. Each of the plurality of candidate timing estimates may represent an estimated temporal location of a synchronization sequence in the received digitized signal. The method may further include demodulating the received digitized signal according to each of the plurality of candidate timing estimates to produce a plurality of reliability metrics, wherein each of the plurality of reliability metrics may be associated with one of the plurality of candidate timing estimates. The method may additionally include selecting one of the plurality of candidate timing estimates as a selected timing estimate based on a comparison between one or more of the plurality of reliability metrics and performing synchronized mobile communications using the selected timing estimate and a frequency offset value associated with the selected timing estimate.
