Abstract: Apparatus and methods for estimating a direct current offset in an upconverter are disclosed. Samples of a first signal are received. Values of a compensation signal are retrieved. For example, the compensation signal can be a component in a modified baseband signal, wherein the modified baseband signal is upconverted, downconverted, and filtered to generate the first signal. An estimate of a first DC offset induced by an upconverter is generated based at least partly on at least two selected samples of the first signal and corresponding values of the compensation signal.
