  • Overview of Synergetic OFDM Crest Factor Reduction and Digital Pre-Distortion for RF PAs
  • 2011

  • Conference paper (other academic/artistic)abstract
    • Digital baseband pre-distortion (DPD) is used to linearize nonlinear RF PAs, crest factor reduction (CFR) to increase the maximum output power level of RF PAs. Together they result in increased output power with maintained, or even, better linearity. This paper discuss some of the techniques for DPD and CFR methods currently under investigation. Measured results for a class-AB PA using OFDM signals indicate a possibility to increase the power added efficiency (PAE) by at least 15%-points, from 30% to 45%, and a power output increase of 6 dB while maintaining specified ACLR requirements.
