Logic for direct current (DC) estimation of a wireless communication packet. Logic may determine a first DC estimation based upon a first set of sequences in a preamble of the wireless communication packet. Logic may determine a second DC estimation based upon a second set of sequences in the preamble. Logic may select one of the DC estimations based upon a frequency-offset estimation. Logic may remove one of the DC estimations from the packet. Logic to null DC bins that result from a Fourier transform of the packet to mitigate transmitter DC bias. And logic to determine a correction for the packet based upon a difference between a predetermined guard interval value and a received guard interval value and to apply the correction to the packet.
