Abstract
Logic for spur estimation of a wireless communication packet. Logic may receive an input signal output by a set of analog-to-digital converters and determine means of sequences for each of the analog-to-digital converters. The sequences may be from a preamble of the wireless communication packet. The sequences may comprise a set of short training sequences with an average zero mean received after logic detects a boundary of the sequences. The set of short training sequences may comprise a Golay sequence Ga and a Golay sequence −Ga. Logic may determine spur estimations for each of the analog-to-digital converters based upon a frequency offset estimation for the wireless communication packet. Logic may remove a mean of the spur estimations from the spur estimations. And logic may remove the spur estimations from the packet.
