An apparatus and method for deriving a digital image correction factor in
a receiver. In one embodiment, a receiver circuit may include an error
detection circuit configured to receive a digital signal comprising
in-phase (I) and quadrature (Q) components and to detect an error in a
complex image correction factor, and an error correction circuit coupled
to the error detection circuit and configured to modify the complex image
correction factor dependent upon the detected error. In one specific
implementation of the receiver circuit, the error detection circuit and
the error correction circuit may be coupled in a feedback loop, where the
error detection circuit may be configured to iteratively detect the error
in the complex image correction factor, and where the error correction
circuit may be configured to iteratively correct the error.
