Patent ID: 7430263

Claim:
A method for timing correction for fast PN acquisition, the method comprising: measuring a first set of measured points, wherein the first set of measured points correspond to a first set of measured correlation samples; determining a set of ideal points; comparing the first set of measured points against the set of ideal points, wherein comparing the first set of measured points against the set of ideal points further comprises: measuring a plurality of correlation samples; assigning a first discrete time to the plurality of measured correlation samples; assigning a time shift in units of samples; determining a theoretical set of discrete magnitudes; determining a correlation function; determining where the correlation function equals zero; zeroing the theoretical set of discrete magnitudes where the correlation function equation equals zero; determining a difference between the theoretical set of discrete magnitudes and measured plurality of correlation samples; squaring the difference; summing the squared difference; and determining an optimum time-shift variable resulting from the comparison of the first set of measured points against the set of ideal points.
