Claim:
1. An electronic device comprising: a memory configured to store pre-defined bias values, the pre-defined bias values including a first bias value corresponding to a first frequency channel and a predetermined transmission power level; a receiver configured to receive a signal of a specific band through an antenna, wherein the specific band comprises a plurality of frequency channels including the first frequency channel and a second frequency channel and the received signal corresponds to the second frequency channels; a channel quality measuring module configured to measure a channel quality of the second frequency channel based on the received signal; a bias offset determining module configured to determine a bias offset based on the measured channel quality of the second frequency channel; a bias offset applying module configured to modify the first bias value by applying the determined bias offset to the first bias value; a power amplifier configured to amplify transmission power of a transmission signal to be transmitted through the first frequency channel according to the modified first bias value; and a transmitter configured to transmit the transmission signal at the predetermined transmission power level through the first frequency channel.
