Abstract:
The present invention provides methods for coarse frequency offset estimation, where those methods may comprise the steps of: removing fading channel impact by calculating accumulated correlation values; removing CCI and phase rotation due to large sampling offset by calculating an accumulation metric as a function of the accumulated correlation values, CCI peak, and initial sampling offset, ξ; and finding the coarse frequency offset as a function of the accumulation metric.
