Abstract:
A method and apparatus estimating carrier frequency offset (CFO) with timing synchronization are provided. The apparatus includes processor that receives analog-to-digital converter (ADC) samples, determines a coarse angle from the received ADC samples, obtains an improved coarse angle by altering the coarse angle based on a preamble duration, determines a base CFO estimate from the improved coarse angle and determines a plurality of candidate CFOs based on the base CFO estimate and a difference frequency.

Claim (Index 12):
The apparatus of  claim 8 , wherein the processor is further configured to estimate the CFO and the timing synchronization using the plurality of candidate CFOs by:\n obtaining a plurality of compensated ADC samples corresponding to the plurality of candidate CFOs, after compensating the received ADC samples with the plurality of candidate CFOs; performing a sliding window correlation for each of the plurality of compensated ADC samples with a oversampled preamble sequence; and determining a maximum correlation value among all correlation values in the sliding window correlation for each of the plurality of compensated ADC samples.
