Abstract
A method and offset removing apparatus for removing DC offset from a digital baseband signal value pair included in a set of digital baseband signal value pairs is described. The digital baseband signal value pairs, when plotted on a complex signal space I-Q diagram, lie on a predetermined figure. The I and Q coordinates of the central point of this predetermined figure are determined by a two-dimensional fitting of this figure through a subset of signal value pairs included within the set. These coordinates of this center point are subsequently subtracted from the I and Q coordinates of the digital baseband signal.
