Patent ID: 7400869

Claim:
A method comprising: determining, during a first expected idle period of a received signal, a first direct current (DC) component of a first amplified representation of the received signal at an output of an amplifier, wherein the amplifier is set to a first gain setting; determining, during a second expected idle period of the received signal, a second DC component of a second amplified representation of the received signal at the output of the amplifier, wherein the amplifier is set to the first gain setting; determining whether a transmission burst preceding the second idle period is a valid transmission burst; when the transmission burst is determined as valid: determining a first average DC component based at least in part on the first and second DC components; and adjusting a DC offset used by the amplifier when set to the first gain setting based on a comparison of the first average DC component to one or more threshold values; and when the transmission burst is determined as invalid: determining a second average DC component based at least in part on the first DC component but not the second DC component; and adjusting the DC offset used by the amplifier when set to the first gain setting based on a comparison of the second average DC component to one or more threshold values.
