Abstract: A method and an apparatus for improving signal quality through noise detection in an electronic device are provided. The electronic device may include a power amplifier configured to amplify and output a transmitted signal, a noise detector configured to detect noise in a receiving band by the power amplifier and to output a power level of the detected noise, and a processor configured to acquire the power level of the noise through the noise detector, acquire control information to change the output power of the power amplifier based on the power level of the noise, and control the output power of the power amplifier based on the control information.
