Design of a Feedback Predistortion Linear Power Amplifier

A new feedback predistortion linearizing method is proposed and analyzed. This method extracts the third-order intermodulation distortion (IMD) signal from the main power amplifier (PA) output signal and the original input signal and uses it as the pre...
Mobile communication systems currently use multi-carrier/multi-channel schemes for effective use of the frequency spectrum resources. The intermodulation has a serious impact on these communication systems in terms of adjacent channel interference, resulting in an increase of bit error rates. As the power amplifier operates close to the saturation region...
