1. A receiver circuit comprising: an IQ signal source configured to provide a digital signal comprising in-phase (I) and quadrature (Q) components, wherein said digital signal is modulated at an intermediate frequency (IF); an image correction unit coupled to said IQ signal source and configured to receive a plurality of periodic functions, each of which represents a respective portion of a combination of a frequency conversion signal with a complex image correction factor, wherein the combination of the frequency conversion signal and the complex image correction factor is determined independent of said digital signal; wherein said image correction unit is further configured to perform a single cross-accumulate operation that combines said digital signal with said plurality of periodic functions to produce, as a result of the single cross-accumulate operation, an image-corrected baseband output digital signal comprising in-phase and quadrature components.
