Abstract:
An apparatus to estimate a frequency offset in wireless networks is provided. The apparatus comprises: radio frequency (RF) circuitry to down-convert a signal from a base station to generate in-phase and quadrature (IQ) components, wherein the signal includes one or more repeated bursts; and a frequency offset estimator operatively coupled to the RF circuitry, the frequency offset estimator to estimate a frequency offset based on the IQ components and an iterative calculation of phase differences between different sets of bursts of the one or more repeated bursts.

Claim (Index 27):
The apparatus of  claim 26 , wherein, to estimate the frequency offset, the frequency offset estimator is to iteratively update the phasor until the assigned iteration number to determine a final phasor (\u201cR M \u201d) based on R n = R n - 1 * e \ue89e angle ( R Ln * conj \ue8a0 ( R n - 1 ) n n \ue89e j , n=1, 2, . . . , M,\n where angle(*) is an operation to calculate a phase of one complex value.
