ABSTRACT:
Methods and apparatus for detecting, estimating, and compensating for unwanted d.c. offsets in sampled signals in a direct conversion receiver are described. These methods and devices can be used for varying d.c. offsets, ramps, and steps to realize a direct-conversion receiver for modem cellular communication systems that does not suffer performance degradation due to strong interferers.
