Abstract
Aspects discussed herein include a method and associated network device and computer program product. The method includes receiving a network packet, and estimating, using a preamble of the network packet, a power distribution corresponding to a plurality of subcarriers of a channel. The method further includes estimating a carrier frequency offset using the power distribution, and estimating a clock offset using the carrier frequency offset.
