ABSTRACT:
A first direct current (DC) component of a first amplified representation of a received signal at an output of an amplifier set to a first gain setting is determined during a first expected idle period of a received signal. A second DC component of a second amplified representation of the received signal at the output of the amplifier set to the first gain setting is determined during a second expected idle period of the received signal. A first average DC component is determined based at least in part on the first and second DC components and a DC offset used by the amplifier when set to the first gain setting is adjusted based on a comparison of the first average DC component to one or more threshold values.
