1. A data processing system, the system comprising:
an analog to digital converter circuit operable to convert an analog input into a series of digital samples, wherein the series of digital samples includes a preamble pattern; an amplitude estimation circuit operable to estimate an amplitude of the series of digital samples corresponding to the preamble pattern received during acquisition phase processing; a comparator circuit operable to compare the amplitude with a window threshold; an acquisition gain feedback calculation circuit operable to calculate a gain correction based at least in part on a result of comparing the amplitude with the window threshold; and a data correction circuit operable to correct the digital samples corresponding to the preamble pattern by an amount corresponding to the gain correction.
