Abstract
A receiver that employs inherent characteristics of frequency domain representation of the data symbols. By computing a differential-in-frequency function across a large number of OFDM tones, robust estimates of time and frequency offset are obtained. The obtained time and frequency estimates provide control to sampling and frequency offset elements that are interposed between the reliever input and subsequent receiver stages.
