Abstract:
Aspects of a method and system for multimode DC offset compensation are presented. Aspects of the system may include accumulating a selected number of signal samples, determining an average of the accumulated signal samples, and keeping a running total of the average for use feedback signal generation. The signal samples may be, for example, samples of WCDMA signals. By keeping track of the signal offset error, the signal offset error, or residual DC, may be determined. For example the signal offset error may comprise a DC component and/or a sinusoidal component. The number of signal samples to accumulate for the average may be based on the signal offset error. For example, a threshold may be determined as part of design of an embodiment of the invention.
