Patent ID: 7813454

Claim:
A wireless signal receiver to demodulate an OFDM signal having multipath components, said receiver comprising symbol timing logic to control the timing of a Fourier Transformation operation by Fast Fourier Transform (FFT) logic, wherein the symbol timing logic is to drive the Fast Fourier Transform logic to perform the Fourier Transformation operation on signal data synchronized to a first multipath component received earlier in time than a second multipath component, wherein the symbol timing logic adjusts a result of an autocorrelation operation by a fixed design constant to generate a signal used to drive the timing of the FFT logic, wherein the autocorrelation operation determines an amount of correlation between a cyclic prefix and a later portion of the OFDM signal that repeats the cyclic prefix, wherein the fixed design constant is predetermined based at least in part on a plurality of OFDM waveform parameters, the fixed design constant being independent of the multipath components.
