Abstract

In a method to compensate for a step DC disturbance (1) in a baseband signal in a homodyne radio receiver, the time profile of the step DC disturbance within a burst is determined. In order to produce a step-corrected baseband signal, the determined time profile (2) is then calculated from the digitized baseband signal.
