摘要: The synchronization technique invention uses inherent characteristics of the frequency domain representation data symbols. By computing a differential-in-frequency function across large number OFDM tones, robust estimates time and offset can be easily obtained. also allows system designer to directly trade performance in presence channel impairments against signal processing complexity. Analysis simulation have shown good noise delay dispersion, that are harshest wireless environment. Prior techniques for focussed on signal. Those recognized translation not considered systematic modification by offsets.
