Patent ID: 7142835

Claim:
A receiver circuit comprising: an IQ signal source configured to provide a digital signal comprising in-phase (I) and quadrature (Q) components; and an image correction unit coupled to said IQ signal source and configured to combine said digital signal with a complex image correction factor; wherein the image correction unit is configured to combine said digital signal with said complex image correction factor by: multiplying said in-phase component by a value of a first function of a real portion of said complex image correction factor to form a first product; multiplying said in-phase component by a value of a first function of an imaginary portion of said complex image correction factor to form a second product; multiplying said quadrature component by a value of a second function of the real portion of said complex image correction factor to form a third product; multiplying said quadrature component by a value of a second function of the imaginary portion of said complex image correction factor to form a fourth product; accumulating said first and fourth products; and accumulating said second and third products.
