  Tiny Digital Predistortion Receiver
  Integrates RF, Filter and ADC
  Todd Nelson The power amplifier (PA)
  consumes more electrical
  power than any other block
  in a cellular basestation and
  is therefore a significant
  factor in the operating
  expense for the service
  provider. Complex digital
  modulation requires
  extremely high linearity
  from the PA, so it must be
  driven well below saturation
  where it is most efficient.
  To improve PA efficiency,
  designers use digital
  techniques to reduce the
  crest factor and improve PA
  linearity, allowing it to run
  closer to saturation. Digital
  predistortion (DPD) has
  emerged as the preferred …
