    Abstract: Systems and methods for estimating and correcting a DC offset in a receiver in the presence of a carrier frequency offset. Samples corresponding to a transmitted signal are received. Each sample is corrected for a carrier frequency offset. An average value is computed for a training sequence of the corrected samples, where the training sequence has a known DC offset. The average value is adjusted using an adjustment factor that reflects an effect on the DC offset of the act of correcting for a carrier frequency offset, thereby generating a DC offset estimate.
