ABSTRACT:
Methods and systems are provided for estimating the DC offset distortion in a receiver. A fast Fourier transform is applied to at least a portion of a preamble portion of the received signal; an impact of the DC offset distortion on one or more empty subcarriers is determined; individual DC estimates are derived based on each of the determinations; and each of the individual DC estimates are combined to obtain an overall DC estimate.
