Abstract:
1. A method for determining a time domain frequency correction for a received signal having a transmission frequency, comprising: a) determining a first frequency correction in the time domain, the first frequency correction having a first maximum frequency pull in range, wherein the first frequency correction is a cross product of a processed pilot data and its time offset version; b) determining a second frequency correction having a second maximum frequency pull in range, in parallel with determining the first frequency correction, where the second frequency correction is a multiple of the first maximum frequency pull in range; c) determining a third frequency correction in parallel with determining the second frequency correction, where the third frequency correction is a multiple of the second maximum frequency pull in range; and d) summing the first frequency correction, the second frequency correction, and the third frequency correction to determine the frequency correction for the transmission frequency.
