Highly efficient three-bit digital power amplifier for ofdm waveform amplification

HIGHLIGHTS

  • who: LICENSE and collaborators from the (UNIVERSITY) have published the article: Highly Efficient Three-Bit Digital Power Amplifier for OFDM Waveform Amplification, in the Journal: (JOURNAL)
  • what: The authors propose a novel three-bit DPA architecture with eight RF output power states, which can amplify the OFDM waveform with high efficiency and low distortion. The authors provide an approach to optimize the linearity by selecting the output power levels through the quantization of the OFDM envelope by considering the statistical distribution that minimizes the EVM. The authors design an optimized power combiner network that performs . . .
