Abstract
A wireless communication system () estimates a carrier frequency offset between wireless devices () by configuring the devices through exchanging packet configuration packets () to specify a carrier frequency offset fingerprint (CFOF) sequence in a measurement packet () which is transmitted between the wireless devices, where the CFOF sequence in the measurement packet includes a prefix component (), one or more signature segments (), and a suffix component () for performing CFO measurements at the wireless devices which each process IQ samples corresponding to the signature segments in the received measurement packet by correlating the IQ samples against a reference vector to generate, for each of the one or more signature segments, a carrier frequency offset estimate between the first and second wireless devices.
