METHODS AND ARRANGEMENTS FOR DIRECT CURRENT ESTIMATION OF A WIRELESS COMMUNICATION PACKET |
摘要 |
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. |

1. An apparatus for direct current (DC) estimation of a wireless communication packet, the apparatus comprising:
high frequency offset logic to determine a first DC estimation based upon a first set of sequences in a preamble of the wireless communication packet; low frequency offset logic to determine a second DC estimation based upon a second set of sequences in the preamble; selection logic to select one of the DC estimations based upon a frequency offset estimation; and receiver DC estimation logic to remove the one of the DC estimations from the packet. |
