Efficiency Comparison of a Digitally Predistorted and a Feed-forward Linearized Doherty Amplifier with Crest Factor Reduction

This article provides a direct performance comparison between a Doherty digital predistorted (DPD) amplifier and a Doherty feed-forward linearized power amplifier (DFFLPA) under various crest factor reduction levels. Based on experimental results at an...

The increasing importance of spectral efficiency in mobile communication services, such as wideband code division multiple access (WCDMA) and orthogonal frequency division multiplexing (OFDM), has resulted in a fluctuating signal envelope. The large peak-to-average power ratio (PAPR) of these modulations requires base station power amplifiers to have a high...
