Patent ID: 6839388

Claim:
A system for providing frequency domain synchronization for a single carrier signal, comprising: a synchronization circuit that is capable of receiving the single carrier signal, obtaining a coarse frequency estimate of the single carrier signal, and obtaining a fine frequency estimate of the single carrier signal; wherein said synchronization circuit is capable of obtaining the fine frequency estimate of said single carrier signal using a frequency error Δf p where Δf p is given by the equation: Δ f p =[1/(2 πNT s )][Arg[ X pr,q (0)/ X pr,q+l (0)]] where [1/(NT s )] is a frequency spacing, and where T s is a sampling period, and where X pr (0) is the transmitted signal with constant frequency error in a zeroth bin, and where Arg[X pr,q (0)/X pr,q+l (0)] is a phase of a pilot carrier signal in the zeroth bin.
