Abstract
Methods () and corresponding systems () for determining and correcting a DC offset in a receiver operate to sample () a signal to provide complex samples; estimate () a Direct Current (DC) offset corresponding to each of the complex samples, the estimating the DC offset further including solving a plurality of equations relating to the plurality of complex samples, e.g., N simultaneous equations in N samples with a power of the signal invariant across the N samples, to deterministically derive offset values; and then remove () the DC offset from the signal.
