Abstract
Some demonstrative embodiments include devices, systems and/or methods of Direct Current (DC) estimation. For example, an apparatus may include an estimator to estimate a DC component of a received wireless communication packet based on a first value, a second value and an estimated frequency offset, wherein the first value is based on a first plurality of samples including at least a plurality of samples of a first sequence of a preamble of the wireless communication packet, the second value is based on a second plurality of samples including at least a plurality of samples of a second sequence of the preamble, immediately successive to the first sequence, and the estimated frequency offset corresponds to a frequency offset between the first and second pluralities of samples.
