• Adjacent Channel Interference for Turbo-Coded APSK

      Rice, Michael; Shaw, Christopher; Brigham Young University (International Foundation for Telemetering, 2008-10)
      A study of the effects of interference caused by adjacent channels on the performance of turbo-coded 16- and 32-APSK. Included in our discussion is the spectral regrowth in the nonlinear power amplifier when driven by a non-constant envelope modulation. Ultimately, we present a set of channel spacing guidelines when using turbo-coded APSK for aeronautical telemetry.
